Yes, I think we are getting there. If List 38 was 1956, that was probably the one and only one that I was involved with. As I left that year, No 39 would be post-me.
I had always assumed that when I saw the Jobling moulds en route for Davidsons some time in the 1960s that the latter had taken the whole lot. With hindsight, there was no justification for that - just a feeling based on the fact that Jobling's engineering management liked to get rid of unwanted stuff fast. It now seems that Sowerbys (and others?) might have been invited to do a bit of cherry -picking.
The big gap between the pattern numbers which I remember and 2684 surprised me because I knew that no way would Sowerbys have had the capacity to produce so much new stuff. That now will suggest that Sowerbys took and re-christened much more than this one vase or suite.
So, you cynic (I forget who) who criticised Sowerbys sequential numbering system, it has its uses!!
