I have always said I'm an accumulator, not a collector. I do shoot my guns, that's what I bought them for.
Most collectors concentrate on a theme, a period or some specific firearm. Many specialize on Colt black powder revovlers, or cartridge conversions. Maybe patent evasions of the Rollin White patent. Winchester lever actions, or military arms.
A friend of mine, who died recently, collected military arms. His collection brought over $50,000.00 to his estate.
But, without some order, it's an accumulation. And I've enjoyed every aspect of my accumulation.
