ROCK ISLAND AUCTION HOUSE ESTIMATES PRODUCTION NUMBERS AROUND 375 EXAMPLES MADE! The Erma ET-22 combines the controls of the classic Luger pistol design and the fun of a plinker. Produced from 1967 to 1969, relatively few ET-22s still circulate within the market. While this gun could easily be a collectible or heirloom, it makes an even better range toy. This Erma ET-22 is the perfect companion for any collector who is in need to a small varmint gun that could also be displayed proudly on the wall.
