Success! I have finally got my 1/16 M4A3 VVSS conversion from the Tamiya M4 105 HVSS on the field! I added a custom made 75mm gun mount, scratchbuilt engine deck, and many small corrections and detail parts to take Tamiya's Sherman back to the mainstream. This vehicle is also a memorial to my Great uncle, a Platoon commander from the 7th Armored division, 40th tank battaliion. "Dorothy" is a nod to my maternal grandmother- his sister.

I had a few wiring problems but now that they are resolved... to the field!
