Thanks Bernard.
Bit confused over your conclusions - there are 8 links, so I assume your numbering follows them.
1. There is no mention of the name on this, only 'British Made' - this could be Chance as it was known to mark products as such.
2. Did you mean this (321356902468) to be the Sutherland Brawn one? The 'Berries & Stem' might fit this design.
3. This link shows five moulds. The rear two are definitely Bagley, but what about the three in front?
After this I'm not sure.
