M100B Cabinet Question

I'm restoring my 100B and the grill (as well as other parts) has been altered at some point in time. I have attached a photo and can take more detailed images now that it is stripped down if needed. I have bought all of the available reproduction parts (cloth, grill bars, stainless triangles, mirrors etc) but i need to restore the structure of the cabinet before I can mount the new parts and I have no reference. It's not hard to find images of complete units but I can't find any of a bare cabinet.
Does anyone have any images or a unit they could photograph? Any help would be greatly appreciated.

Thanks, Ozzie
