So.... what do you have inside it?
At times I've had spare barrels for a Model 29 S&W and Ruger Blackhawks. A hammer for a three-screw Super Blackhawk, ejector rod housings (alas, aluminum), ejector rods, grip frames for Rugers (aluminum and steel), assorted springs and screws. Trigger for three screw and New Model Rugers, a transfer bar, a couple of rear sights, and some unidentified parts.
At times I've accumulated enough parts to justify buying the gun for them.
I did have a pretty good stock of Colt Government Model parts and/or M1911 parts, but sold/traded most of these off over the years.
