Shotguns, All Types - TM 9-285 War Department Technical Manual

a. This technical manual is intended to serve temporarily (pending the publication of a more complete revision) to give information and guidance to personnel of the using arms charged with the operation, maintenance and minor repair of this materiel. b. This manual contains in brief the available information necessary for the identification, operation, care, and cleaning of the shotguns listed below. In addition is included the disassembly and assembly of the guns for the purpose of cleaning and lubrication, and available information on ammunition. Shotguns covered in this bulletin are as follows: Winchester Repeater, 12-Gage, Remington Repeater, 12-Gage, Winchester Repeater, 12-Gage, Remington Repeater, 12-Gage, Stevens Repeater, 12-Gage, Remington Auto-loading, 12- Stevens Repeater, 12-Gage, Remington Auto-loading, 12- Stevens Repeater, 12-Gage, Savage, Auto-loading, 12-Gage, Ithaca Repeater, 12-Gage, M37 c. Disassembly, assembly, and such repairs as may be handled by using arm personnel will be undertaken only under the supervision of an officer or the chief mechlanic. d. In all cases where the nature of the repair, modification, or adjustment is beyond the scope or facilities of the unit, the responsible ordnance service should be informed in order that trained personnel with suitable tools and equipment may be provided, or proper instructions issued. a. The shotguns covered in this manual are of various makes, models, and types. In some cases different models of the same make differ widely in design, in others the differences are principally in detail of design. Each make of gun herein is treated separately and where there is extreme variation in model, the model is treated as a separate gun. Where slight variations occur in different models of the same make, they are grouped and the differences explained as they occur. b. Instructions for disassembly and assembly, and special care and maintenance are covered in the section pertaining to the gun and in section XI; while cleaning, lubricdtion, and general maintenance, which are more or less common to all the guns, are covered in section II, covering the Winchester M97 gun, and can be applied in general to the other guns as indicated. c. A general description of the gun for identification, together with such identification marks as may be found upon the gun, are given at the beginning of the section pertaining to the gun in question. a. The repeating shotguns covered in this manual are of two general types, the slide action, sometimes termed pump action, and the autoloading or semiautomatic. The autoloading gun is often called an automatic, which is incorrect as the trigger must be pulled for each shot. b. As already explained, different models of the same make of gun may vary in design in whole or in part. Also guns of the same make and model but of different grades may vary slightly in design. In addition some guns of the same make, model, and grade but of various dates of manufacture may have slight variations in design. Such variations are dealt with as far as possible herein. Other variations which may appear must be dealt with as such. c. Due to absence of standard ordnance nomenclature for the guns covered in this technical manual, with the exception of the Ithaca M37, the parts and assemblies are given the nomenclature supplied by the manufacturer and appearing in their parts lists. Therefore parts and assemblies of, for example, a Winchester gun, may be referred to by a different name than similar parts of a Remington gun.
