Can only think of two examples. Clark Gables Sheridan SuperGrade and Prince Charles air rifle in the NRA firearms museum in the US. Seems to be a lot of firearms notable by their owners but not too many Airguns? Any other examples? I suppose you could say Lewis and Clark’s Girardoni is one of the most famous but not sure it’s really ever been found?
