A 1941 yr/mfg according to a list I have.
The magazine matches (ser#) which is a big plus.

The electro pencil marking does take away from it, but it is what it is.

Nice pistols in .22RF.
One was my carry gun for nearly 35yrs.
An early 60's mfg Walther PPk in 22rf, I bought used around '74 w/ 2 xtra mags.
Now gone and replaced by a MArlin Mod 97 Deluxe rifle in .22 in a straight trade.
Harder to conceal, but shoots nice too.
