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.
I can say that your Browning BL-22 was made between 1970-2003 by Miroku of Japan.
No way to tell without more of a description.
You will need to look in old gun catalogs, Blue Book of Gun Values, etc..
Depends on how old it is. Have it checked over by a good gunsmith
