Hi, the problem is, as both Mark Hill and I will confirm, that there was just so much glass, which came out of Kamenicky Senov, with cutting that was pretty much time-less, that a journal such as CGR, could not possibly ever have covered every single design. Though I have spent large amounts of money, not on glass, but original research materials, I have not yet managed to find catalogues from the post-war period, with the type of work, for which Ivo and Norman are seeking information. It is true, "Dual", as a series was well thought of, but little else in the way of "cut-to-clear" was ever considered really worthy of coverage.
Regards,
Marcus
