I recently bought a solid silver albert chain and would like to find out a little more about it.
I cannot seem to locate an "City" mark to be able to date is properly, it has the maker marks R.P and the date letter N (capital) I did suspect it was Robert Pringle & Sons but the date letter N doesn't correspond with the years they were in operation.
Hopefully someone here can help me solve this puzzle.
Thanks in advance
