The internet is always a good place to start. If you can find anything, call a local gunsmith in Yellow Pages. They are often willing to help for free. 410 models are small and generally worth less than larger gauges. Double barrels arr worth more than single. Models from the 1940's and '50's were cheap guns. Selling for $60 to $80, today it should be worth at least $100 if it fires and maybe upto $350... good luck.
