Kriegsmarine U-boat clasp in bronze 1st pattern – Schwerin, Berlin

Kriegsmarine U-boat clasp in bronze 1st pattern – Schwerin, Berlin. Zinc 1st pattern semi hollow ‘U-Boot Frontspange’ with bronze finish. Remains in in unworn mint condition with all the finish showing. Soldered on setup with round base plate, wide pin and slightly factory vaulted appearance. Very rare variant that easily 20 times rarer than the 2nd pattern examples with crimped hardware. Top piece that is nearly impossible to find with this much finish remaining.
