The wooden forearm is easily made, but if you need the metal part of the forend you are in for a tough time. We are one of the largest used parts dealers in the country and have not had a Crescent .410 forend iron in years. sales@countrygunsmith.net
"The Berkshire" by Meridan Firearms "Berkshire No. 3000" by Crescent Firearms Contrary to popular belief, not the same company.
The Crescent Arms "Empire Hammerless" double barrel (20 guage) is not a collectable gun, but is a "shooter". Thus, in shootable condition, it is worth about $200. That's what I paid for mine, strictly for bird hunting.
If it is a hammerless single shot or double barrel, it was PROBABLY made by Crescent Firearms, 1892-1931.
150 USD
The only Crescent shotgun that I know of that was nickeled was the 20 guage, 14 inch barreled Knickerbocker. A shotgun with a barrel length of 18" or less requires a Class C license from the federal Bureau of Alcohol, Tobacco & Firearms. Assuming you are correct and it is a 12 guage, it was originally blued and parts should be available from http://www.gunpartscorp.com.
$100-$250.
$100 to $250, depending on the exact model and its condition.
Circa 1890-1930. Would have to have more information to get closer. sales@countrygunsmith.net
