I've been looking for an M33 for awhile and not had a single lead. I want to build an M13 replica so my plan is to turn an M45 into an M33 or at least a reasonable facsimile. I'll probably never get to it but I'm going to give it my best shot. The only M33 I was even able to get pictures of was an original mounted in an International in the UK or Europe I forget which. Even though most if not all of the M13's were winch models (except the one in the manual, lol) I'm going to use a really nice M15 cab/chassis I have.
