Jay Glass was set up by John Deacons (1978 to 1983). Allan Scott joined John as lampworker in 1979, but weights were all "Deacons". When Jay Glass closed, Allan went to Caithness Glass where items he designed or made were "Caithness".
It's the person who does the encasement, or the Company for non-studio work, that is regarded as the maker. But lampworkers and cutters do get credit sometimes, particularly for studio work and this is more so these days. It's good that in many of the current Scottish weights the other workers do get a fair share of the recognition.
