Like many, I often wonder why I got rid of a lot of the nice now-old stuff I had years back when it was then-new? Acquiring better, more interesting stuff was usually the motive, as well as a need for money.
When I wish that I had kept everything, I remind myself that I'm a very average, run-of-the-mill person. So, had I kept all the now-cool stuff, so would have everyone else.
Consequently, if we had kept everything, most of the guns we now hold dear would not be nearly as desirable and hard to get, and many of us would be stamp and bottle cap collectors instead of gun enthusiasts.
That, or something similar, helps me get through the envy I feel when I see something like the above 1950 ... for a while, at least ... Thanks for sharing your find ...
