If there are no Belgium Proof marks it may be a J.C. Henry Arms Co shotgun. This was a Trade name used by this distributor from St Paul MN on guns made by Crescent Arms Co around the 1900's
If There are Belgium proof marks it may be a Henry Gun Co which was a trade name used on Belgium Imports from around 1900.
The marks should be on the water table of the shotgun
yeah looks very similar to the one pictured. has some pitting on the barrel but the bore looks real clean. the action isnt scored up either. its had some use but doesnt look like a whole lot. the stock isnt in bad shape either. it would need to be refinished. worth the $75 they are asking?
