As already suggested by @Zodicab here for USSR I would like to suggest the recaptured German vehicle for Germany.
The 76,2 cm S-1 auf Pz.Kfw.III or in German intelligence documents also called simply “Sturmgeschütz 76” or “Sturmgeschütz 76 (r)”
From the German perspective its is completely logical to recapture and use the vehicle, as the hull and most parts are German and the gun uses the standard 76,2x385mm ammo, which ever Germany produced and used their own. (Also in T-34 and so on).
This would also make it slightly more different to the Russian used one, as it has different (better) ammo available as well.
Historically speaking (see more above in the original post above) the SU-76I (I standing for Inostrannaya (foreign) was created out of need by the Russians. In Fall of 1941 the Red Army had a great need for a light SPG armed with the standard 76mm gun, but demands were not meat until December 1942, until the normal (and in game SU-76M that later appeared) was ready. However production demand was still not met, as such Factory #37 Started to convert Pz IIIs and StuG IIIs to use a F-34 (Standard T-34 gun) in a fixed casemate.
Another project was the mounting on 122mm guns (SG-122) which were overloaded and less successful, however 181 were build with additional 20 Command vehicles.
And as such also some were recaptured and reused.
Germany itself captured lots of different guns, reused them, updated and improved them (reworked mountings, drilling out to 714mm casings, new muzzle brakes and new ammo (Pzgr.39, Pzgr.39 Rot, Sprgr.39, Gr.38 Hl/B and C, Pzgr.40) for all of them.
And here i suggest the recaptured German Sturmgeschütz 76 (r), knocked out in late 1943 was a SU-76I from the 128 Pz.Jg.Abt. 23 Pz.Div.
Now to the other special part, Gun and Ammo.
While standard captured Russian ammo is also used, Germany produced (with 385 and 714mm casings) own ammo for the all of the guns, modified and not.
