As a person who collects & appreciates stuff "as shipped" I like to see as many saved as possible. Between various events over their lifetime,, (1955 to 1963) the Flattops have been dwindling in numbers. (Fires, floods, LEO destruction, exports, customs, bubba destruction, etc,)
As a collector,, it just drives up the values of those left as is. That's good for people like me. But it also makes it harder for a newer collector to find an example to start a collection. And having a "less than perfect" condition one is where many collectors buy one while searching for one in better condition.
I get parts to where if I find a gun in need of restoration of something,, I can "fix" it. And the old FT's,, well, there are minor differences in the triggers,, and that may be a little harder. The grip frame & grips,, a little easier to replace, but still not quite as easy as replacing later stuff. (XR3 vs XR3-RED.)
Yeah,, it's a little cold in our areas right now,, and range time isn't fun. And it can also affect how well a gun can perform due to the "loose nut behind the trigger."
Shooter grade, rougher protected sighted guns are more plentiful. To give you an idea,, there were approximately 42689 FT .357's built. There were approximately 243551 protected sighted guns built. That's 200862 MORE protected sighted guns built than the FT's.
