Good question....I think it would work OK depending on how you position the figure on the turret...If you want him in the turret hatch, it looks like it may be necessary to drill a hole for the extended leg.
cnq, Have you tried to adapt the FL Russian Tank commander with the Figarti T-34???...I am going to try to drill out the hatch opening so that this figure will work with the Winter Figarti T-34. If I can get the opening large/deep enough to accept the extended leg of this figure it should work. Otherwise it should work seated on the outside of the turret hatch.... Let us know how your doing with it as well.
