Star Model F series .22 cal Pistol
Starting in the early 1950s, Star began producing a series of small-caliber sporting and target pistols. The models were the F, FM, FR Sport and FR Target. All appear to have been built in .22 LR and carried 10-shots. The primary differences appear to have been in barrel length and profile. The FM has a 110 mm barrel, the FR sport 150 mm and the FR target 180 mm. All appear to have drift adjustable rear sights, and all are single action. A simple model F is depicted at the right.
