Great piece Michael! These are just as rare and interesting as early Beranek and are all really part of the same story, as you know, it is not necessarily impossible that Beranek made some of these pieces before heading to Skrdlovice. I think they are not easy to find either. CMS and early Beranek do not seem to have had widely different production numbers, of this type of qualty glass. Amazing how infrequently these things appear for sale worldwide, on ebay, auction sites or at fairs. The departments making this stuff at both sites cannot have been sizeable concerns at all, rather specialist... Jindrich was lucky to find one catalogue, it is the only one I have really seen, what a helpful document it is too. A piece a lot like this was at Sypka once I think, but the do not appear often do they?
