Mick G,,let me try to explain,the gun laws here in the uk are a mine field,yet it wrong and it's At least five years in the clink or shot by a swat team,,first a revolver must be made before 1899 uk,,1898 in the USA to be an antique,certain calibres are obsolete they're collectors items if held in a collection,,modern ammunition can't be used as the pressures are to great,the gun would blow up,,,if black powder bullets are acquired for these weapons they then become a section one firearm in which case a firearm certificate is needed and a license to buy black powder and somewhere legal to fire it,,,,,These are just the basics,,best thing to do is leave them alone the authorities don't want guns in private hands,,a gun collector now has to live the life of a monk,one misdeed and its porrage every day and fish on Friday.
