That's a mighty fine one! My grandaddy got me one just like it (1955 vintage) when I turned 12. He kept it "for me" but it was mine If I behaved all week, when we went fishing Saturday I would get a coke, a candy bar, and a box of WW 22s to shoot.
For me, it's my old Regulation Police targets. Just fun to shoot- no drama. I got a thing for .32's. Most likely going to son#3 along with the Ladysmiths (which he has dibs on in no uncertain terms!)
On the subject of birthday month/year S&W searches, I have been lucky four times. The Holy Grail/Golden Unicorn to me would finding ANY S&W that has the Roy Letter showing shipped 11/13/47. The model doesn't matter, caliber doesn't matter, even condition is not critical... just the lettered date.
Still looking. -Bill
Although not as nice as any listed here, I recently picked up a M17-3 with a 1975 mfg. date. It matches my son in laws year of birth. Cleaned, it is one of my top shooting handguns. It will be a great gift for him someday.
