Greetings: Here is a recent conversion of a Heng Long M4A3 Sherman to an M-7 variant which includes a Vandra resin upper hull, a 3D printed 105mm Gun and lots of scratch built parts. This was a very challenging project as no instructions were provided, so if anyone else out there has one to build, PM me and I can send you a 66 page set of color instructions that I wrote.

Very nice. Ludwigg makes an m7 kit as well, though his qc is hit and miss.

The Vandra Kit was ok but just hard to figure out how to fit it together w only pictures to go by. I also relied upon a build thread that was here on RCU quite a while back. So now I have a full set of build instructions (66 pages) for anyone who wants them. PP
