Russian weapons v4

After a quick search, I found some pictures of the SU-122-54 aka IT-122.

SU-122 and SU-122-54 are two different vehicles because one uses the hull of a T-34 and the other uses the hull of the T-54. Additionally, I believe SU-122-54 was developed to be a tank destroyer. I have no clue how many of them were produced (one translated Russian site says only 77).

I haven't found anything about World War 2 SU-122s having their howitzers being upgraded to the 122mm D-49. During World War 2, the Russians tried to replace the howitzer but those tanks failed during the trials.
