Do percussion doubles, made in the 1870-1880 time frame count as a gun and have to on a certificate? Are there problems shipping them out of the country? In the US they are considered to not be a gun and can he shipped or sold with few restrictions. Importing them is easy as pie for us. Are they a problem to export.
Any gun that will (or may be) be used is still 'a gun' and subject to the usual gun licensing. My percussion gun is licensed because it is usable.
Where a gun is antique (and no ammunition to suit is available) it may (subject to never being intended for use) be held without license.
It is a bit of a 'grey' area, but for for muzzle loading shotguns - which have not been deactivated (and certified as such by the proof house) you would normally require the usual license.
