The MG 34 was offered commercially by BRNO after the war because it was a gun they could build and for which they had a good supply of components. Most were sold to the Israelis, but others went elsewhere. Some were code dot45; I have seen at least one, near new, that was unmarked, and obviously came from the factory that way.
The ZB26/30 bipod is actually one of the best ever designed, a far superior unit to the bipod on the GermanMG 34 or 42. It is very steady, adjustable, spring-loaded, instantly deployed or folded and stays put.
