Good job on recreating that part Jason. When I'd thought that was one of the last parts of this to be found, I must have spent months trying to get a peek at every kit from the era in order to figure it out. It looks like a glacis plate+fenders from a tank, or SOMETHING with fenders, but darn that's a hard one to figure out.
Looking forward to your parts run. I probably have most of them, but might just use your castings so I can spare some kits and let them back out into the wild...
