Library, internet, Standard Catalog of Firearms.
Perhaps a good place to start would be to find a copy of Flayderman's Guide to Antique American Firearms- you may be able to request a copy through your local library. This is a fairly comprehensive book with good descriptions and illustrations of thousands of antique firearms. You might also check for gun dealers in your area that know antique firearms, or check out a local gun show, where dealers in antique firearms have been neatly gathered in one spot for your convenience.
In firearms, antiques are LEGALLY defined as made prior to 1899, OR muzzleloading firearms. Newer than 1899, they are old, but not antiques. My best reference is Flayderman's Guide to Antique Firearms. You may also find a dealer or collector that can share some information with you. Check for gun shows in your area.

L. Richards was a maker of antique flintlock firearms, such as their No. 6 pistol. Unfortunately, they are fairly rare, and there is no public records database for MOST antique firearms. Sorry.
There are several websites which deal in vintage firearms. Some of the most popular are Gun Broker, Vintage Weaponry and Antique Arms. These websites both buy and sell firearms.
