Just for shits and grins, i searched "gatling Gun" on Youtube.. Knowing there's 1/2 dozen out there over the past 20 years, and NOW it's the age of the interwebs...:shrug:
10 pages deep.. i don't know if the guy says WHERE this one came from.. :shrug: Donn would have most likely stained the wood, and he loves to make brass knobs and handles and stuff anywhere he can..
But if Donn did not build this one, i would be very surprised, as most his look identical to this one...
and they work very well..
