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.

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.
Check the owner's manual, or check with Mossberg customer service. Unless the choke is rated by the maker for steel shot, not good to do.
Can you Yes, should you NO. a full choke should not be used to shoot slugs.
