There were some Shotguns Stamped Rev-O-Noc H.S.B. & CO. that were made by Hopkins & Allen. They were distributed/retailed by Hibbard Spencer Bartlett of St Louis, Mo. Rev-O-Noc shotguns made by Crescent were also distributed by Richards and Conover of Kansas City. They were also manufactured by Baker Gun and Forging Co and Iver Johnson Arms and Cycle Works. HSB & Co was in Chicago.
Made by the Crescent Firearms Co. If it is marked as AMERICAN GUN CO, it would be 1905-1922. If marked as CRESCENT FIREARMS is would be 1922-1930.
AFAIK, there is no published sn data on Crescent Arms.
These shotguns would have a flaming bomb arsenal mark on the gun.They would also have United states property marked on the shotgun.
I would try the numrich gun parts corp.They can be found on the web.
Depending on the condition and configuration, it would run from $100 to $250.
Circa 1890-1930. Would have to have more information to get closer. sales@countrygunsmith.net
Trade name used by a hardware company in Pennsylvania. Actual manufacturer could be one of several such as Iver Johnson, Davenport, Stevens or Crescent. Any parts, including stocks, would undoubtedly have to be made and fitted.
Crescent was in business from 1892 to 1930. If it is a hammerless gun, it was not made before 1903. Value would be from $150-$250 and the Redhead recoil pad is an addon but it's not going to deduct anything from the value like it would on a high-end collectable.
Are you sure it doesn't say Genuine Armory Steel? That would make it a product of Crescent Fire Arms. There should be more markings if they haven't worn off.
Would need to know exactly how that gun is marked.
50-125 USD or so
No new parts would be available, but a competent gunsmith could probably make one.
