That is a real mixed bag
That is a Profiline Resin hull. Best cast hull I have ever seen, Unfortunately I don't think they are available anymore. Although I think Taigen or Torro might have bought the molds.
The Tub is Mato with metal suspension
The 3 piece tranny cover was something I imported from the Netherlands
Mato Brass gear box
My own turret casting, and a lot of other Scratchbuilt features. All the headlight guards etc were fabricated out of flattened brass wire.
I have a pile of Sherman's Just putting the finish touches on Fury which can then be added to the stable..
