    The front cone is recessed, with holes drilled on the periphery, and assembles into the outer casing of the muzzle-attachment in place of the ball pattern front cone.
  • Cat No. C1/BD 0665, List of changes A7792 GUNS, MACHINE, VICKERS, .303-IN., Mk. I, Cups, muzzle-attachment, Blank, Mk. I – For Mks. IV A and IV B guns

    The muzzle cup has a large recessed seating to house the head of the adjusting screw and is assembled to the D.P.B. barrel in the usual manner.
  • Cat No. C1/BD 0772, List of changes A7792, GUNS, MACHINE, VICKERS, .303-IN., Nuts, Adjusting, Muzzle-attachment, blank – Also for Guns, machine, Vickers, .303-in., Mks. IVA and IVB (Section C2)
    The adjusting nut is of the ring type with holes in the outside edge to accommodate the spanner. It assembles to the projecting end of the adjusting screw and locks against the face of the front cone.
  • Cat No. C1/BD 0902, List of changes A7792, GUNS, MACHINE, VICKERS, .303-IN., MK. I, Screws, Adjusting, Muzzle-attachment, Blank, Mk. I*, No. 1 – Also for Guns, machine, Vickers, .303-in., Mks. IVA and IVB (Section C2)

    The adjusting screw has a large concave head drilled longitudinally for approximately one inch and is screwed into the front cone so that the large end may enter the muzzle cup. (The original screws were drilled throughout, these have now been plugged at the foremost end).

    The muzzle-attachment washer is for use with the Mks. IVA and IVB guns to prevent the unscrewing of the front cone when used in A.F.Vs. It is a thin steel washer with 3 tags (two long and one short) and assembles between the front cone and outer casing. The long tags are turned into the openings of the outer casing, the small tag being turned into a spanner slot of the front cone.

Deflectors and eliminators

The issue of noise, blast and flash is dealt with in all Maxim and Vickers manuals from the early periods of machine gun use, with both being obvious concerns 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.

Silencers

An early Minute of the Small Arms Committee recognises that the noise of rifles and machine guns would give away the position to the enemy – they were not concerned about the impact of the noise on the firer.

116. Attachments to Rifle for other than Shooting Purposes.

“Silencer” for Rifles and Machine Guns.

The D. of A., 31.5.1904, notified that several proposals for a “silencer” for rifles and machine guns had been submitted lately. Trials conducted with two of them, Mr. Keeson’s and Capt. Kirke’s, had been unsatisfactory, though it was possible the defects could be remedied if an appliance of the kind was wanted. The objection to the idea seemed to be that it would add to equipment, increase its weight, and being applied at the muzzle would injure the shooting and prevent rifle having a bayonet. Rapidity of fire would also be diminished. The same objections applied to some extent to its use on a Maxim gun.

He asked for the views of the Committee as to the necessity for an appliance of this kind. A sample of Mr. Keeson’s silencer was forwarded.

The “silencers” so far submitted are only effective in close proximity to the gun, and do not prevent the report of discharge carrying to a distance. The Committee consider that such an application is not required, but if one could be designed that would entirely arrest the report of explosion, they are of opinion it would be useful.

Minute No. 859 of the Proceedings of the Small Arms Committee, 6 June 1904.

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.
