I have a KM stamped Lyman peep sight for a Marlin 22 pump, fits models 20-29-37-47.
Pretty nice shape.
I need a vintage peep sight for a Marlin 1893.
If anybody wants to do a trade, hit me by pm.
I'm interested in trading so, if you ask me my price, I don't have one, make an offer.
Pics to interested parties.
