IGC is the Internet Gun Club (http://www.internetgunclub.com/Home.aspx)

It is a magnificent resource of gunmakers names. It has been and continues to be a labour of love by one man, researching in depth any gunmaker or person in the gun trade.

The biggest problem though is that the site runs on a bespoke platform that has always presented problems. Sometimes access is straightforward, sometimes it's frustratingly impossible!
