The Champion 410, a shotgun model produced by the Champion Arms Company, was primarily manufactured in the 1980s. Specific production dates can vary, but the model is generally associated with that era. If you have a specific serial number, you might be able to identify its exact manufacturing date through resources or databases specific to firearm serial numbers.
I bought a champion singel shot 410 about 8 years agon for $129. It does not have a serial number on it. The gun is old but I don't know how old. No cracks in the wood.
Your .410 probably uses the short shells and is of the vintage of about 1908 give or take.
