A little progress. My Accumount mount came with 45 degree set of rollers, which corresponds well to the drop-in mount they sell, but is NOT right for a real ZF41 base, which used rollers of about 70 degrees or so. There were lots of as-cast surfaces. The Accumount version (unlike hte Numrich version) also did not come with a set screw on the underside of the front ring. Finally, the Accumount copy had a piece of drill rod as the latch pin, while originals had a pan-head pin.
These inaccuracies would just not do. So I went over the entire mount with either and end mill or a file, follower by a light 120 grit sanding with a light 60 grit sand. Gives hte impression of a part that was tumbled after machining like the originals were. Then I machined a new set of 70 degree rollers from bar stock and installed them, locks up MUCH tigher now on my French repro base. After that I machined a new pan-head pin and installed it. Finally I added a 4-40NC set screw under the front ring.
Much better. After bluing, it will look like a post-war refurb of an original mount (nazi markings removed). I also serialized it in the original style.


This shows how a repro can be made to look original, though only crazy people like me would do so. Originals only sell for $75-100 more than the reproductions, so it's not worthwhile for most guys to fake these yet
