I believe that Constrictor didn't actually manufacture the hubs themselves, but had their name stamped on hubs made by other manufacturers. Some of these were foreign (French?) and some, like the BOA pedals and some of the cranks (and possibly wingnuts) were made by BSA.
There's a rare French Super Champion Derailleur on eBay at the moment (item
280122304319) which is stamped "Osgear" on the arm, which, as you may well
know, was Constrictor's brand name for the derailleurs they imported and
sold in the UK.
