Black plastic Mk5 Rifle Oil Bottle

In the past we have looked at the brass Mk IV oil bottle for the Lee Enfield rifle here. These brass oil bottles were very well made, but heavy and used a valuable resource, brass, that could be better employed in making cartridge cases. During the Second World War a new design, the Mk V or Mk 5 was introduced that was made of plastic. Not only was this lighter, but it did not use a valuable commodity such as brass in its manufacture. Early bottles were prone to warping, but by the end of World War Two the design had been perfected and the bottles would continue in service until the 1990s. A number of variations of the oil bottle was produced and tonight we are looking at some of the more common black plastic examples:imageEach bottle is made of black plastic with a knurled section near the lid to aid grip. Unscrewing the lid reveals a plastic rod with a small spoon like tip that is used to precisely place oil in the right parts of the weapon:imageA rubber washer is fitted to help seal the oil inside the bottle when the lid is attached:imageLike many of these bottles this one is now starting to show its age and the rubber has dried and perished. A variation can be found in the lid of the bottle, with some being plain and some having the initials ‘DCP’ and an arrow logo moulded into the plastic:imageUnfortunately I have not been able to determine who actually made them and which company used this logo. These bottles were not only used with the Lee Enfield rifle but also saw service to carry mineral oil in the Bren gun spare barrel bag and as part of the SLR cleaning kit after the war. These humble bottles are still very common and can be found for a couple of pounds each.

  1. I found a container like that in the butt of my AK47. I’ve had it for 25 years and never knew it was there. I’m trying to send a picture but it won’t let me paste it here
