Ralph, did that revolver have gold medallion walnut stocks?? Transition to convex stocks took time since lots of inventory would have been manufactured in 1919. Let me know if it was not gold medallion, since I can find no references to walnut K frame convex stocks. I frames did wear convex walnut stocks well into the 1920s.
Added: I checked my 1920s catalogs to find the round-butt M&Ps were listed with walnut stocks, so I now have to find a gun with the convex walnut round butt stocks.
