Winchester Model 1300, Ranger Compact
http://www.winchesterguns.com/products/catalog/historic-detail.asp?family=012C&offset=24&mid=512036


The Ranger® Compact has everything you need in a shotgun — only in a smaller package. With a length of pull of just 13" and a drop at heel of 2 3/8", speed to the shoulder and rib alignment are ideal for smaller shooters. The inertia-assisted Speed Pump™ rotary bolt makes pumping not only faster, but also much easier. The forearm is positioned rearward (see picture and compare) for a shorter reach, making it easier to work the action. The grip area is smaller for better finger-to-trigger fit. It's complete with the versatile WinChoke® system for excellent shot patterns. Available in 12 and 20 gauge.
