My serial No is 3360879 Miroku skeet gun? any idea.Thanks Roger.
I’m looking for information on my 20 GA BC Miroku OU with matching serial # M360960. I’ve read about date identifying letter codes but my shotgun has no such letters
I have a Browning GP Sporter 12-gauge O/U shot gun serial number T 57298ZY, I know the year of manufacture is 2012, could you tell me where it was made please.
My Citori serial number does not match the format you show. It is 09672N57.
I’m guessing they used the previous format for a while, where the last 2 positions defined the year.
I found:
37=1973
47=1974
but they never defined 57 which I presume = 1975
Thanks!
The serial number on my 12 gage Miroku shotgun is 542197. I bought it in the 1960s. Anything you can tell me about it?
