When I saw that George III's private papers, along with his children's, were online, figured it was worth a look to see the bills of Samuel Staudenmayer. Of course, Staudenmayer is the most famous of all London airgun makers. I've long maintained that the airgun carried by Meriwether Lewis on his famous journey was most likely made by Staudenmayer. That Staudenmayer made Girandoni-type airguns is well established, there's a wonderful example residing in the Milwaukee Public Museum collection (I've seen it in person. It's totally black. Not a bit of shiny or brass visible. Blacking a gun was a very common thing with the military at the time. This example also just happens to be missing the rear sight. Something that Capt. Lewis commented on occurring to HIS airgun, too.) But, some have questioned exactly when Staudenmayr set up his gunmaking business in London. Some have placed this as late as 1807. But, here's the absolute proof that Staudenmayer was in business in 1799. Here's his bill to George IV for a shotgun.... dated 1799.
