With regards to these grips on a Triple Lock:
Would the silver coloured medallions be appropriate or the gold coloured ones only, and is there a specific time frame for each?
Having said that, mine are gold coloured on most, if not all, of my Triple Locks, but at least one are replacement vintage N frame grips. The one pictured, however, is 100% correct in all respects...gold medallions, shipped in 1916.
When and on what models would silver have been appropriate for if only gold is appropriate for the Triple Lock?
What is the metallic composition of both the gold and silver medallions?
