Introduced in 1922. Model 39 was chambered for .22 rimfire, had 24" octagonal barrel and take-down receiver. Has full-length magazine tube which holds 25 Shorts, 20 Longs or 18 LR cartridges. Most Model 39s had a spring-loaded button outer magazine tube release. Very early variations had Model '97 type knurled latch release. As Model 39As were being phased in around 1939, many have more modern removable inner magazine tube. Has solid top frame and side ejection, Rocky Mountain rear and ivory bead front sight. Receiver, lever and hammer are case colored; barrel blued. Pistol-grip stock and steel-capped forearm are varnished walnut. Manufactured in this form between 1922 and 1938, with a number of options that could affect value and would warrant an individual appraisal. Model 39s with a "star" stamped on tang, were considered high grade guns by factory inspector and will command a premium in better condition examples. NOTE: Model 39s made prior to 1932 that have no prefix or prefix S on serial number, should not be used with high-speed ammunition. Prefix HS indicates an improved bolt that is safe for this ammunition.
