I had a mate here , a charcter like your self , Pro Hart ( look him up , artist)
i made cannons for him , because he was a famous sort of artist and loved guns Pro took on a lot of the early fight back , sort of a spokesman ,
anyway , his stuff was good and showed the aussie outback , but wasn't valuable ,
now he's passed , things with his name .. WOW ! ..
google that too
when he was just a mad miner who liked black powder weapons , shooting and did paintings to see to tourists , i got a few off him as payment for small job's , i've a few of a few aussie artists , stuff from gun smiths , engravers of note , etc
one day that piece is gonna be worth something more than $$$ because what it is who made it , no blowing sunshine no where ok ?
theres you , holmes ( and i've built his too and published fixes , especially the pistol )
mintrand or whatever the frog guy is and thats it , since about 1710
Phil Luty , i class different , he's Phil , Bless him also passed now , great fighter for gun rights in the UK and great improvised weapons designer, they locked him up again for his work and he died in gaol from his cancer
they let the lockerby bomber free.. Phil , a gun rights campaigner .. nada ..
document it all , make up a package , and do it that way
folks who like this sort of thing and have a eye for the future will jump
that'd never fly here as a licensed import , but by heck , i'd give it a good run for it's money for a collectors as it has a package from the maker , it's unique , ( for now )
