Simmons Hardware Company used the "SH Co" logo .
Crescent Fire Arms used various names for "house brand" shotguns and this may be one of them. They used other companies to make shotguns for them. Hartford Arms actually made the guns for both Simmons and Shapleigh Hardware. (Shapleigh bought out Simmons Hardware in 1940)
So S.H. Co would be a house brand name made by Hartford under a Crescent contract. Hartford Arms & Equipment made guns from 1925 to 1932 and was bought out by High Standard Co in 1932. Crescent was bought out by J. Stevens Arms around 1930, and they continued to make "house brand" guns for several years.
The water table is the part of the receiver that the barrels of a double barrel or single shot break-action shotgun rest on.
I would look at the number of barrels. If there is more than one barrel, you know you have at least a double barrel shotgun. If there are 1 or less barrels, then you don't.
The cartridges will pop out.

Nerf has recently debuted the Barrel Break IX-2, a double-barrel shotgun that uses Whistler darts. It has very short barrels, though. If you want a longer one, you can go to BuzzBee and their Double Shot weapon.
I'm not sure of the value of your shotgun. I have a Montgomery Wards Hercules, double barrel shotgun, with external hammers. With all the research I have done it is a Stevens 217. I have been looking for a set of barrels for this gun. Can you describe your gun to me. Petter
