Hi all,
I had a look again to this interesting topic.
I think that the style of rails for the sliding hood makes the idea of La-5F more likely than of a La-5FN.
The early style of canopy, predominant on La-5F, had a slighly curved upper profile, and its rails at first raised a bit (but this part is hidden by the canopy itself), then were slightly descending, parallel and close to the window's edge, and had not a vertical slot at its end. Exactly what we see on this photo.
The later type of canopy was jettisonable; it had straight upper profile, and rails parallel to the lower frame of the sliding hood, far and not parallel from the frame of the rear canopy, and end with an upwards slot. It's not fully clear when it was introduced, but it's by far the dominant type on La-5FN.

Hi Massimo,
if you increase the light and you reduce the contrast, we can see the heat-protecting panel of a La-5FN
