Winchester Model


The Winchester Model 1907 Self-Loading rifle, later called Model 07, was introduced in 1907. Designed by Winchester engineer Thomas C. Johnson, it was essentially an improved model of the earlier Model 1905 rifle which also had been designed by Johnson.

The Model 1907 rifle is blowback operated and is chambered for the .351 Winchester Self-Loading cartridge, a cartridge made for use in this arm only. It fires a 180-gr. bullet at a muzzle velocity of 1856 feet per second (f.p.s.). Muzzle energy of this cartridge is 1378 foot-pounds (ft.-lbs.).

Breech mechanism of the Model 1907 rifle is of so-called balanced type in which the breechbolt assembly is proportioned in weight to the weight and velocity of the bullet. It was so designed that the breech remained sufficiently closed until the bullet had left the barrel.

A 20" barrel was standard for this rifle. Both 5-shot and 10-shot detachable box magazines were offered, the latter having been made available in 1911.

The Model 1907 Police rifle was authorized in 1934. It was equipped with \Va" sling strap and could be had with detachable knife bayonet.

Manufacture of the Police rifle was discontinued in 1937, and the sporting rifle was discontinued in January 1957.

Disassembly Procedure

Check action to be sure rifle is unloaded. Press in magazine lock (D, Fig. 1) and withdraw magazine (19) from bottom of receiver and guard assembly (1 & 18). Cock hammer, loosen takedown screw (22), and separate guard and buttstock assembly from receiver and barrel assembly. Buttstock can be removed from guard assembly by removing buttplate (not shown) and unscrewing buttstock bolt (23) through hole in rear of buttstock. Buttstock may be drawn off the tang of the guard assembly to the rear.

Unscrew forearm tip nut (8) using a suitable spanner. Slide nut forward on barrel. Tap forearm tip (6) forward off forearm, and draw tip with operating sleeve (10) and operating sleeve spring (9) intact forward on barrel. Remove spring (9) from sleeve. Note that operating sleeve is pinned to operating sleeve tip

(11) and cannot be separated from forearm tip (6) without first removing pin

(12) and tip from sleeve. Pull wooden forearm (not shown) forward away from front edge of receiver (1) and off front end of bolt.

Bolt spring (15) can be removed by unscrewing bolt guide rod (16) from front end of bolt while holding bolt (17) in its rearmost position. Withdraw bolt guide rod and draw bolt forward. Remove bolt spring (15) through opening in bottom of bolt, taking care not to allow compressed spring to escape forcibly.

Note: Since reassembly of bolt spring (15), guide rod (16), buffer washers and buffer (13 & 14), and bolt (17) cannot be accomplished without factory tools, disassembly of the bolt is not recommended and should only be attempted by a skilled gunsmith with the proper tools at hand. Disassembly of the bolt is seldom if ever necessary for normal cleaning purposes and maintenance. Reassemble in reverse.

1 Complete guard assembly is shown here. Since the respective retaining pins are staked in place at the factory.

disassembly of this component is not recommended and should only be undertaken by a competent gunsmith.

2 The bolt assembly is shown disassembled here. Firing pin (BB) and spring (CC) are removed by drifting out pin (AA). Extractor (EE), spring (GG), and plunger (FF) are removed by unscrewing the screw (DD).

3 After loosening takedown screw (22), pull receiver and barrel straight forward slightly to disengage lug at forward end of guard (18) from corresponding groove in front end of receiver (1). Lift barrel and receiver assembly from guard and buttstock assembly.

4 When removing forearm tip nut (8), a suitable type of spanner wrench should be used as shown to prevent damaging nut. After unscrewing nut, slide it forward on barrel to allow forearm tip (6) to be moved forward, away from front edge of wood forearm. ■
