A lot of these vintage ones from about forty years ago are constantly coming on the market as their elderly owners pass away and/or sell their firearms. Most of these J frames were not shot much, if at all.
They aren't rare by any means, so if one is patient they can find a "good deal" occasionally. However, with vintage S&W revolvers, what is defined as a "good deal" changes every few months . . . and no matter what price you pay . . . one day you'll wish you could have bought five at that price later!
IMHO, $450 is a little strong . . . unless they have the full "kit" (box, all original materials, manual, cleaning brush, etc.).
PS: Here's my new (to me) 1964-made Model 36 "no dash/diamond stocks numbered to the gun/square latch" snubbie. I paid $350 for it less than three years ago . . . but prices keep going up on the fine, vintage S&W revolvers . . .
The first shot was right after I got it . . . with just only a hint of a turn line on the cylinder . . .
And a couple of more current shots of the same revolver . . .
