Hey everybody, I'm just doing a bit of research helping out a mate who wants to know what these makers marks actually mean, can anybody "translate" these for me please? Thanks in Advance
The SP has across various proof houses been used to indicate Special proof, Black powder proof and also Smokeless proof....in this case it may be the same or a Miroku specific mark.... research required...or maybe an email to the Aussie distributor.
The 'SP' and 'NP' are just proof marks from the Japanese proof house TBD. My Browning ablot2 rifle made my Miroku also has NP stamped on the barrel as it's made in japan.
Miroku have a date code using two letters and you will have to locate the stamp. For example, PN=1989.
