A friend of mine gave me this nice buckle.
A perfect fit for my one-hole ABP croc, although not strictly period correct for a 1950 ref. 2605. The tongue cut from sheet is very nice compared to the old stamped versions.
Here in Oregon by the guy I bought it from. He only did it as a favor though 'cause he felt kinda obligated since he's the one who sold it to me. He doesn't really work on them any more. I have some names though if you're looking. They're recommendations from other people but I have no direct experience with any of them.
