Vintage Oil Rig Pump Jack German Silver Belt Buckle Turquoise Mother of Pearl

A vintage hand crafted German silver belt buckle featuring an oil rig and pump jack. Inlayed with what I believe to be Turquoise and Mother of Pearl.

Does state L/W on the back, most likely the maker but I can''t find any info about it.

This is a rare piece given its subject matter. Does have surface scratches but still usable and nice quality.
