May I suggest a book (not the Web) called "2008 Standard catalog of Firearms" it's huge and list all types of firearms. I've traced guns back into the 1800.
gunpartscorp website is one place to start looking. The maker of the gun is another.
It will depend on the individual venue. Call up the venue, or check their website to see the age requirements.
to find the old bratz website go to google and type in the old bratz website.

Crosman Corp owns Benjamin Air guns. The name Benjamin Franklin was a marketing ploy to sell the guns. Benjamin Franklin had nothing to do with it. Older air guns are no longer repaired by Crosman however they offer a service to find independent repair shops that do service and repair on older air guns and rifles. Go to the link listed below, Click on "find a service center" when the link opens
you can find the old copies of a website from archive.org
You need to find some books by Joe Vorisek. They are hard to find, but "Shotgun Markings" is probably the one you want to identify the manufacturers of old trade-name guns.
