I have seen the design in old catalogs before but am not familiar with the solid silver catagory either. Yale headquarters in the US had a copy of every catalog from number 1 up but in 1992 while I was working 400 miles away Williams Holding made the stupid move of throwing every one of them into the trash. This is likely in a catalog 20 years either side of 1900, so if someone has those you may be able to discover more. Good luck.
BBE.
