From what I read it is a real gun and not a make-believe. Talk about you cheap Saturday Night Special. I am guessing it is a .22 cal short and I would not trust my life to that thing. Interesting to see that it could not be shipped to California, New Jersey and North Carolina, but it could to New York.
The ad is from an early 1960s magazine that it got accidentally thrown out before I jotted down the detail. I do remember it was “Gentleman’s Magazine” of some sort with pictures of women that nowadays would be seen in the Saturday coupon ads you can find in the newspaper.
