Hi, Being new to collecting belt buckels i have three available to me for purchase one is a RZM marked piece and the other is unmarked both have the same hardware the unmarked one has more ware and the two are made of aluminum the third is made of steel and painted black this one too is unmarked with about 80% of the paint intact. They all show the same quality, different stages of ware, guarenteed original ( stright from the vets wife) came from the battle of monte casino. I want to offer his widow a fair price but again I'm new to collecting. Any help would be appreciated. Thanks
