What is the value of a 12 gauge double barrel shotgun made in 1970?
50-100 or so
the knickerbocker was made by crescent arms Look under Crescent Tryon firearms
The Knickerbocker double barrel 12 gauge shotgun was manufactured by the Knickerbocker Arms Company, which operated primarily in the early 20th century. However, specific manufacturing dates can vary, as the company produced firearms from around 1901 until it ceased operations in the 1930s. To determine the exact date of a particular shotgun, one would typically need to reference its serial number or consult industry records.
There is no way to determine the gauge without seeing the gun. Assuming it is one of the standard gauges, you can measure the inside of the barrel. 12 gauge is .729", 16 is .662, 20 is .615, and a 410 is .410.
