Not sure about Belguim Gun Co. but I used to own a New England. It is durable, cheap, and fun to shoot. You can find some online for as cheap as 65 dollars.
They are worth about 50 to 150 dollars depending on who you sell it to and for how much.
We would have to know exactly how the gun was marked to answer that question.
are you talking about the 2-piece .410 that says scout on the side?
Crecent arms made guns under several different names, Bridge was one of them. The exact age of this Shotgun I can't tell you, but Crecent did make a 410 Crecent shotgun around 1930.
The last shot gun made by Midland Gun Co. was in the late 1950s. I got this answer from.....enquiries@bwildandson.co.uk
Bridge Gun Co was a trade name used on guns made for Shapeigh Hardware Co., St. Louis, Missouri, c. 1920-1940. They were made by various manufacturers, but a .410 single shot is likely to be an Iver Johnson Champion.
