K98 bayonet frog marked J. De Valk A’dam 1943

Excellent late war K98 bayonet frog manufactured out of smooth black leather. The frog is nicely marked J. De Valk, A’dam 1943 which indicates this bayonet frog is produced by a Dutch company in the capital of Amsterdam during the occupation. Nice bayonet frog in unissued condition by a rare and desirable manufacturer!
