gun shop

I've inherited several guns with my fathers passing, wonder if any of you folks can help me price them before I take them to a gun shop / show ?

there is a 410 single (winchester) dating from the mid '30'

a Stevens Model 28 Crackshot .22 w/ a curly cue lever and a falling breach (sold for $2 new in 19teens

and a Parker double 12 g hammerless both barrels either modified or improved don't know which, it was made as a grouse gun for my great grandfather (south Ga.) it is one of the base model Parker's ... no scroll work... last patent on it 1911

Look on http://www.gunbroker.com and see what they are asking. Remember there's asking and selling too. There is a blue book of guns that will be pretty accurate for those. The 22 is probably worth around a bill. The Parker and Winchester might be worth a few bucks.
