This is just a convenient way to pass on these images of the various Soviet SPG's I have in my collection
On the storage box, these are described as being IS2 and IS3 tanks but I am not 100% sure this is accurate.....
I think above and below may be ISU 122
SU100 winter camo
All these are just guesses based on the apparent size of the armament and the chassis they are on ...I believe SU were on the T34 track system and ISU on the IS track system....
