This Winchester manufactured third variation complete receiver assembly void of the word "Winchester" on the belly is for the model 37 Steelbilt single barrel shotgun in 12 gauge and is in very good condition retaining a decent amount of thinning original blue finish with the balance exhibiting a brown patina and containing some minor specks of rust. This is the only part on the model 37 Steelbilt shotgun that is tracked as a firearm therefore it will need to be transferred through a dealer. Receivers do not qualify as a C&R based on BATFE's guide lines.  (file photos)

Note: Third variation receiver assemblies have been found with either the intermediate variation or late variation cocking lever (hammer).
