Deflectors and eliminators

The issue of blast and flash is dealt with in all Maxim and Vickers manuals from the early periods of machine gun use, with both being obvious concenrs when siting a machine gun position. Blast, with the resulting dust and mud, is a maintenance issue as well as one of concealment, whereas flash is concealment alone.

To manage this, early developments were extremely simplistic, but later developed into most robust items.

  • Stove Pipe Attachment.

The earlist type which consisted of a tubular arrangement that fitted over the fore portion of the water jacket and extended forward over the muzzle attachment.

General Routine Order 797 dated 23 April 1915. Machine Gun Equipment.

Approval is given for the issue of the following stores for use with machine guns:-

Ammunition box carrier 1 per machine gun
Stove pipe attachment 1 per machine gun
Hyposcope 1 per machine gun

Indents to complete to above scale should be sent to Ordnance Officers concerned, and issue will be made as supplies become available.

Later items became simple and easy to carry, and were often left attached to gun other than when in transit cases.
