Yes. They're "pewter", really a mixture of tin/zinc or maybe tin/lead. Glued them together with CA- typically about 4 to 6 pieces each one. They were released by FASA as kits (to go with FASA's ST game) and, some years later, by Rawcliffe Pewter as assembled, unfinished collectibles with pewter stands instead of the transparent plastic.Nice KBoP.
Are those metal?
