Where can I find information on a Parker Brothers shotgun using the serial number?

There are numerous good books on the market (although some are now out of print) covering Parker shotguns. The internet, of course, might also be helpfull. The two books I have on Parkers are. 1. "Parker America's Finest Shotgun" by Peter Johnson, Stackpole Books. 2. "The Parker Gun" by Larry Baer, Beinfeld Publishing. I suspect that both of these are now out of print, you might get lucky in a used book store though. Another good source concerning values and serial numbers would be the current edition of Fjestad "The Blue Book of gun Values". Any major book store should carry new copies of this pricing guide. Good luck
