The most noticeable characteristic of the kit of LaGG-3 made by the Ukrainan firm Toko (later Roden) is the wide choice of alternative parts that allow to reralize nearly all the versions with very little adaptation work. In origin, Toko produced one kit only, then it was replaced in the catalogue by three kits relative to different versions, containing different decals sheets but the same pieces.

The kit of series 35 has decals for : Grigoryev's yellow 6, with many victory starlets and green/black camo; Lvov's  red 30, green/black with partial winter white overpainting; a photo of this aircraft shows that it had only the part of star on the stabilizer, while the rudder was entirely worn white; besides, white paint has extremely soft outlines; Finnish LG-1(actually a series 4) and LG-3, green/black with yellow bands; note that the blue of the swastikas is too dark, and codes on the right side should be camo green (on black/yellow background); the black prop blades should have yellow tips.

The pieces are neatly moulded in light grey plastic. There are fine recessed panels and rivets, plus some overposition panels; all this is more realistic than the usual stereotyped entirely recessed panel lines that are standard on most kits.  A wide part of the aircraft was made by Alpha wood, so these surfaces are without panel lines.  The reproduction of fabric covered surfaces is good. The details of the cockpit interior are fairly good, including  an instrument panel with two decals, a two-piece seat (which rear plate should be thinned and its sides should be bent forward), a detailed floor, a too large control column, side details and a radio deck. The main undercarrage is composed by fine doors, legs, actuators and fair wheels (but with a too narrow center disk; it could be replaced by one advanced from a Eduard La-7); the bays are rightly deep and their details (or lack of details) corresponds well to that of the real subject. The outlet flaps of the coolers should be thinned on the internal side. A wide choice of alternative parts is provided:  two spinners: piece 40, sharp, for series up to 32, adding a 12,7, 20 or 23 mm gun protruding from the spinner made by rod;  piece 39, rounded, for type 33 and later; three oil cooler intakes: piece 27+30 for series up to 3 (?)(with step); pieces 28+31 for series 4 up to 35 (without step); pieces 29+32 for series 60 up to 70 (large step). three pairs of tail vertical surfaces: pieces 11(r)+12(l) for series up to 6; pieces 15 (r)+16(l) for series from 7 to 34; pieces 13 (l)+14(r) for series 35 to 70. three nose upper cowlings; two water cooler inlets: piece 19 for all versions except for 35; piece 21 for series 35;  two water cooler outlets: 24 is the most used for all versions; 23 is rare on photos, even if some sources show erroneously its generalized use till series 11; three pairs of exhaust stacks: pieces 65 up to series 23; pieces 57 for series from 26 to 35; pieces 55 for series 60 to 70; two tail wheel cover: 35 (not retractable) for series up to 29 36 (retractable from series 35 to 70) and occasionally on some examples of earlier series; eight RS-82 rockets and relative rails, for version 11 or higher; two drop tanks, for version 11 or higher; two rudders: part 18 for series up to 22; remove the lower balance weight for series 4 to 22; part 19 with cracked profile (that will require to cut the stabilizer to fit it) for series from 23 to 70; two pairs of upper wing surfaces: parts 7+8 with slats for series 35 and later,  parts 9+10 for earlier versions without slats;  note that versions with slats have the pitot probe under the right wing, while versions without slats have the probe on the right wing leading edge; in both cases, the probe has to be rebuilt, being the one of the kit (part 68) very unrealistic. The engine cowling upper panels are three:  piece 4 (2+2 guns) is for series 1 only, and, occasionally, for some examples of versions up to 7 armed with 2+2 guns; piece 5 (1+2 guns) is for series between 2 and 7; piece 3 (1 gun): is nearly good as it fis for series 60-70; only, for this model, the side profile should be a bit bend instead that straight (I would leave it as it is); for series from 11 to 35, one should remove both exhaust cover plates on the sides; for series 8, one should remove both exhaust cover plates and fast locks (the small reptangles), replacing them with dzud locks (small holes as for large screws). For all cowlings, two holes should be opened on each side where a 12,7 mm is.

The fuselage halves are nearly perfect for series 11, but require some modifies for reproducing other models.
For earlier series,  the modifies required on fuselage halves are:

• series 11: on many aircrafts, the air intakes on the cowling sides are no longer protruding, but recessed (the left one is replaced by an oval one, the right outlet is replaced by a small recess);
• series 8 and: file a small step on the sides of water cooler outlet;
• series 4: file the small step,
• series 3: file the small step, reshape the exhaust shield plate as shorter and with rounded edge, remove fast locks (small reptangles) from the pannelling of nose lower cowling;
• series 1: file the small step, reshape the exaust shield plate, then add on it an oblique slot, then replace the cowling side inlets and outlets with wider and flatter ones, then add three slots on the left side only, remove fast locks;
• I-301 prototype: file a wider step on the sides of water cooler outlet, remove the exhaust shields, remove fast locks.

• series 23: modify the stabilizer to fit the angulated rudder, add a small antenna mast on it;
• series 29, 33, 34, 35: modify the tail as on series 23, remove the exhaust plate;
• series 66:  modify the tail as on series 23, remove the exhaust plate, add a vertical panel line on both sides under the first exhaust stack, add a small outlet on the left side (?), fill the rear of the slot for exhaust stacks, care the fitting of the longer type sliding canopy.

• oval with a narrow inboard side for I-301 and series 1;
• reptangular for series from 2 to 35;
• wide oval with 3 vertical bars for series from 60 to 70.

front of series 1, with oval wingroot intakes, five guns, one-piece exhaust stacks, oil cooler intake of first type, dzud locks on lower cowling panel.	front of series 4, with reptangular wingroot intakes, four guns, one-piece exhaust stacks, oil cooler intake of second type, fast locks on lower cowling panel.	front of series 35, with reptangular wingroot intakes, two guns, three-pieces exhaust stacks, oil cooler intake of second type, fast locks on lower cowling panel, side panels divided in two pieces, large ventral water cooler intake.	front of series 66, with oval wingroot intakes, two guns, six-pieces exhaust stacks, oil cooler intake of third type, fast locks on lower cowling panel.

The kit provides two canopies, one (piece 42) for series 60-70 only, the other one (piece 43) for all series before 60 (66 in particular). They are fairly good, but both windshields are a bit thick and too low, being their front/side edge cut too back; the front flat panel is too small, it can be a bit enlarged by deleting its frames and repainting them on a more external position. Besides, we see that the piece 42 is longer than 43, because (in series 66) the sliding part was partially overposed to the rear fuselage; this will require some arrangement; here are some possibilities:  shorten the edge on the fuselage,  smooth both fuselage edge and canopy internal edge to allow overposition,  replace canopy with a vacuformed one; choose another version but series 66. Clear pieces include the rear pilot windows, the one for landing light (not for series 60-70, that hadn't it) and for a ventral camera.

One could try to resume in one table the pieces to use for each version and the eventual modifies that could be necessary.
The evolution of LaGG-3 during its production was gradual, and different series built in different factories at the same time could differ in details.
