Belt buckles by treverica

[Latinitas]

Not to be rude, but I think that the best way to replicate this type of buckles is to cast the individual pieces, eventually hammer them and or elaborate them with chisels, and then braze them together instead of casting them as a whole with the decoration carved in the wax model. An other type which you can see in the attached document seems to be the cast version of these soldered/brazed buckles.
