Glad you were able to find one, had a #68 mold a few decades ago but sold it (also a few decades ago) without realizing just how classic it was. For those looking into this thread, Accurate Molds makes a 68 clone in flat and bevel base. I have three of his molds, including the 45-200H, and they are top notch.

45-200H and 45-200HB about 3/4 of the way down this page: H&G 68 clone

Gunnery, gunnery, gunnery.
Hit the target, all else is twaddle!
