In like "new condition", expect to pay around $1000 in a retail store.
You will have to contact Miroku to find out.
Miroku guns made under their name does not have serial info published. Winchester, Charles Daly and Browning have all been made by Miroku in the past. Do you have a model?
You will have to contact Miroku
The letters NZ in the serial number indicate that your Miroku made Browning was made in the year 1991.
If it was made for Browning you can tell by the serial number.
Miroku was making shotguns for different firearms Companies before Browning came along. Charles Daly was one of their biggest customers for shotguns. More info is needed to determine which gun you have. This is not a Browning serial number.
Basically impossilbe to tell a model number by the sn.
No way to tell from just the serial number.
I believe it was known as the "Black Shadow".
Virtually impossible to identify the model of a weapon with just a serial number.
2006 if it is using the Browning date system
The firm B.C. Miroku of Tokyo, Japan made the Charles Daly name of over and under shotguns from 1963 to 1976. Not a lot is known about this firearm, as retaining data apparently was not thought important when they were being sold. This shotgun has a value of around $700.
