Most of the Mossberg bolt action shotguns are worth $50-$90. They are well made, durable firearms, but are pretty much a "working man's" gun. They are reliable guns, but have little collector interest. However, they have been a first shotgun for a lot of young hunters, kept behind the kitchen door of a lot of farms, etc. Made from about 1940-1947. Model changed to 185 in 1947, in production until about 1970.
Many of the Mossberg bolt action shotguns used a removable choke, not an adjustable. Sold under the name C-Lect-Choke, this was an external choke that could be unscrewed with a special wrench, and a different choke screwed into its place.

About $100, depending on condition. The Mossberg bolt action shotguns are inexpensive, but the .410s seem to bring a few $$$ more.

C-lect choke is an adjustable choke system that Mossberg implemented on their shotguns pre-1977. After 1977 they went to the accu-choke system. The choke is adjustable between Full, Modified, and Improved Cylinder. It is, however, not recommended for use with steel shot.
Have it checked by a good gunsmith and ask for advice.
