I've checked almost all the units of the mod for SC and IMHO graphics for two units from R35's list are already in the mod:

SU-11 is ZSU-37 and
37 PstK/36 is 37mm_wz_36 (in Polish units)

I join the previous posts and I thank H.Balck, R-35 and Brazenman very much for your joint and fruitful work.
This is really a New Year gift for everyone who wants to play PC with the updated graphics.
