Other than the gun and mantlet are there any significant differences between the JSU-122 and JSU-152? From what I can tell there isn't but I thought I'd check. I am looking at using the Czech Master 152 barrel & mantlet on the Dragon 122 kit.

Hey Gary,
IIRC, the only difference between the ISU/JSU-122 and ISU/JSU-152 was the gun mantle, cannon barrel and the internal stowage.
Dragon used to also make a ISU/JSU-122S/152.
The ISU/JSU-122S used the same gun barrel as the IS-2 Stalin tank and a ball type gun mantle.
It's unfortunate that their ISU/JSU-122, 122S/152 and 152 kits are OOP.
Hopefully, when Dragon gets around to releasing their Premium edition IS/JS-2 Stalin kits, they'll als do Premium versions of their various ISU/JSU SP's.
Cheers

Besides the gun & mantlet, I don't know.
