One more thing:
075 76.2mm AT-Gun - has a picture of PAK-40, should be 30502 IF it is L51 indeed.

However, as for all 76L51 guns (units 020, 055, 066, 075) I'd rather expect, that they are standard late war ZiS-3 M1942 L41 - weapon 60 from Soviet OOB, with range corrected to 203 (real 13.3).
Correct picture then is 14139 (used for unit 282 in Soviet oob, but very unclear) or Polish 29377 or 101.
