Winchester M-37 .410 Shotgun Break Barrel

The Winchester Model 37 ".410 pigtail" is a highly desirable, early-production (1936-1937) single-shot shotgun featuring a distinctive curled, "pigtail"-shaped barrel release lever. Known as "Steelbilt," these .410 gauge models often feature "red letter" markings on the receiver, making them valuable, sought-after collector items. 
 
Key Details of the Winchester Model 37 Pigtail
  • Production Era: Early Model 37s produced between 1936 and approximately 1937–1938 feature this unique lever.
  • Designation: Often called the "pigtail" due to the curly shape of the top-lever used to break the action.
  • Gauge/Model: The .410 bore is particularly sought after and commands a higher price among collectors compared to 12 or 20 gauge, with the 28 gauge being the rarest.
  • "Red Letter" Connection: Many pigtail models are also "Red Letter" versions, where the word "WINCHESTER" on the bottom of the receiver was filled with red enamel paint (discontinued around 1948).
  • Characteristics: Typically features a 26 or 28-inch barrel with a full choke, an exposed hammer, and, on early models, a "skinny" hammer spur. 
  • Value: Because of their early, "pre-war" configuration, these guns are highly collectible. A .410 gauge, especially in fine condition is among the most desirable variations.
  • Condition: Original, unmodified condition with the original finish significantly increases value.
  • Alternative Models: Later, the "pigtail" lever was replaced with a more standard cast lever on later 37s and the subsequent 370/37A models. 
The Winchester Model 37 ".410 Steelbuilt" is a highly regarded single-shot, break-action shotgun produced from 1936 to 1963, known for its durable steel construction and, in early models (1936–1937), a distinctive "pigtail" top lever. These light, 3-inch chambered guns were marketed as affordable, reliable tools for hunting.
