According to a reference thread in this forum, as well as the SCSW 4th edition, these were used 1910~1920, but on which guns? Would these have shipped on all non-military N-frames in this period, or just some? Is there any kind of reverse-lookup for these kinds of grips? Thanks.
I believe the correct name is "Checkered Diamond Service Stocks with Recessed Brass Medallions". Example from a completed auction attached.
