Well, if you are going to include the big picture, some of that surplus junk sold to suckers included hundreds of original 1853 and 1863 Colt Navies, in VG to Fine condition, for as little as $20 each, back in the 1930s and 1940s. Most of these are worth $1,500 to $3,500 today.
I think they also included many of the 1873 Colt Artillery models, sold at the turn of the century for $12.00 or so, which are worth upward of $5,000 today.
