These are a set of wood target grips for S&W K-Frame-Square revolvers. I don't know who made them, they don't quite match other known manufacturers such as Herret, Sile, etc. They have a few dings and rubs. They're a good match for SA shooting with a longer-barreled target revolver such as a K38, K22, etc. I shoot DA only, so they're not a good fit for me. They came with the K38 I bought years ago. Chances are they are of similar vintage.
Sold pending funds.
