You will need to have it examined by a competent gunsmith to get a definitive answer.
The barrel will be marked with the ammunition it uses. A 500A is a 12 gauge and can use any factory made ammunition that's up to 3" long. That includes all 12ga birdshot shells either 2 3/4" or 3", all 12ga buckshot shells, and all 12ga slugs of the same lengths.
Depends on condition and features. $75 to maybe as much as $250.
No new parts would be available, but a competent gunsmith could probably make one.
go to gunstocksinc.com then look under misc. shotguns the fore arms are $25.00 i just ordered one myself
I found a set for my Enders Special Service a.k.a. crescent on eBay of all places. It took some time and alot of questions, pictures and measurements but was worth the wait. There are many barrel sets that will fit with a little tinkering.
Yes.
0.08" 0.08 is for aluminum...12ga steel is .1046in
Whatever a yuppie will pay for a mantle decoration. Probably $150-$200. Laminated barrels are not considered safe for use with modern ammunition.
It should.

You won't find history of any particular Crescent double barrel model. They basically made one or two models and marked them with whatever name the retailer wanted. Well over 100 different trade names have been found on Crescents. The company was formed in Norwich, Ct, in 1892 and bought by H&D Folsom Sporting Goods the following year. Around 1926 Crescent was sold to Stevens (which was already owned by Savage) then merged with NR Davis (which they also purchased) to form Crescent-Davis Arms. The Crescent name disappeared completely about 1932.
