Research regarding Cookers, Portable, No. 2

[Colin Alford]

Investigation of Operation of Cookers, Portable, No.III, Mk.II and No. I (Hydra Type).* 14 Aug 44, from Capt, W.M.Campbell M.E.3.(b). to M.E.3 CMHQ

See the full document attached.* It includes a sketch of the modification detailed in Army Council Instructions, 24 November 1943; 1725 Equipment - Cookers, Portable, Nos. 2 and 3 - Improved Modification for Burning Leaded Petrol.

While this report is on the Cookers, Portable No. 3, the burner assemblies on the Nos 2 and 3 are identical aside from the length of the vaporizer tube.

The timeline from design to mass production on the Cookers, Portable, No. 2 (Mark 2) Stoves:

A reasonably complete timeline can be derived from the following sources:

5.***** Royal Army Ordnance Corps, Quarterly Reports on Research Work and Experiment; and
6.***** Chief Inspectorate of Stores - Didcot, Fortnightly reports showing new patterns, etc., under consideration with progress to date.

RAOC Quarterly Reports:

Item No:* 86
Objective Requirements:* Cookers, Portable, No. 2
Research and Experimental items in hand and contemplated:* Re-design

Progress and Position on 31 Dec 1942: "Modified designs have been produced incorporating a simplified burner & adaptation of the cases to retain the reservoirs in position.* Experiments are partially successful and are being continued."* Link:* http://heritage.canadiana.ca/view/oo...6/1370?r=3&s=1

Progress and Position on 31 March 1943: "...Experimental patterns are on trial and reports are awaited." Link:* http://heritage.canadiana.ca/view/oo...6/1363?r=3&s=1

Progress and Position on 30 June 1943: "Modified designs have been approved and supplies ordered."* Link:* http://heritage.canadiana.ca/view/oo...6/1357?r=3&s=1


Chief Inspectorate of Stores - Didcot:

Item No.: 15 (16 for No. 3 Cooker)
Cat No.:* JA 0275 (JA 6483 for No. 3 Cooker)
Designation:* Cookers, Portable No. 2
Requirement:* To re-design to make suitable for leaded petrol
Progress on 2 Oct 1943:* "No 2. - Production held up for want of certain raw materials."
**************************** "No 3. - Production proceeding. 1000 a week expected after 6 Oct 43"
Link:* http://heritage.canadiana.ca/view/oo...6/1819?r=3&s=1


Progress on 16 Oct 1943:* "No. 2 - Production in hand"* Link:* http://heritage.canadiana.ca/view/oo...6/1817?r=3&s=1


Unfortunately the rate of production for the No. 2 Mark 2 is not stated and I have not found any concrete information regarding a date that the Mark 2s got into the hands of the troops.* The following document does seem to indicate that at least some Mark 2 stoves had been issued by 26 Jan 1944

A very brief discussion of Australian production:

I have not purposefully pursued any research on Australian production of Cookers, Portable, No. 2.* In my early research I found some references to them but I didn't save any of the discussion or images.* From the limited data I can recall or can access quickly I believe this is a reasonable summary:

It appears that the A. Simpson & Son of Adelaide, Australia produced cookers based very closely on the British design.* These stoves embossed with Simpson on the lid may have been for a military contract.* Later military stoves have D /l\ D embossed in the same location on the lid.

There was an MLU thread (that I saw recently but I currently cannot find the link) which discussed a modified Australian stove. My recollection of the images showed a stove which retained the original case and detachable fuel tank and substituted an "S"- shaped fuel feed pipe with an attached burner.* This burner appeared very similar to the British design for their Mark 2 stoves. This may have been the Australian solution to the lead problem.

A good set of images of an Australian produced stove can be found here:

If any Australians are interested in contributing to the knowledge base it will be much appreciated.

Canadian Stoves:

As previously stated I was frustrated that I could find no evidence of Canadian produced Cookers, Portable, No. 2 but I have come to believe that the reason I could not find the evidence was because I assumed that the Canadian Cooker would have been based on the British model.* I did not imagine that it would be a substantially different design.

It appears that collectors of Camp Stoves have been aware of these models for some time but the knowledge of them does not seem to be widespread in our Militaria/Military Vehicle community.

Unfortunately I have only been able to find limited evidence online but I believe I have found enough to make a relatively convincing argument to support my claim that the Canadian version of the Cookers, Portable, No. 2 was in fact a Coleman Model 500 Speed Master Stove which was stored inside a cast Aluminum Pot which was based on the British design, and secured by a leather strap which was shorter than the British equivalent.

I will present this evidence in the order that I encountered it:

The first evidence was the April 1943 Stowage Chart for the Ram II tank.* Item number 76 is described as "Cooker Portable No. 2, Pots, Cooking with lid Stove, Strap" but the image only shows the Pot, Cooking with lid and the Strap.* At this point I did not think that Canada might be using something other than the British design stove

The second source of evidence were these 2 images from the Library and Archives of Canada site (copies attached below):

*http://collectionscanada.gc.ca/pam_a...=e010778901-v8

http://collectionscanada.gc.ca/pam_a...=e010778902-v8


I could see that the stove was not a British No 2 but I could not make out exactly what it was.* I still didn't start to think that there might be a "Canadian" stove but that maybe the crew was using a privately purchased stove.

[Colin Alford]

The third piece of evidence that I noticed was the 20th image of original Ram interior photos on this page: http://www.ramtank.ca/ram_interiors.htm* (this image is also in the Ram II Operator's Manual but it is very dark and very small)

Again there is only the pot and strap visible and I thought that maybe the reason why the stowage diagram didn't illustrate the (British) cooker was because there wasn't one available for the artist to draw.* I still did not think that there might be a Canadian cooker.

The kijiji ad was the final piece of the puzzle that caused me to start believing that Canada must have had it's own design of cooker:* (images attached)

I then re-visited all of the previous images and realized that while I thought I was thought seeing a British pot, (Pots cooking, with lid) there is the obvious (once it is pointed out) difference in height.* I also started to think that the reason I could not see a stove in the stowage diagram or stowage picture was that it was actually stowed inside of the pot.

[Colin Alford]

I had a couple of discussions at the fall OMVA meeting about this topic and it was suggested that maybe all that this proved was that a special stove was issued with the Ram Tanks.* This prompted further investigation.

Jordan Baker identified the Model number as a Coleman 500 Speed Master and provided me with these links:

In the above image of B-squadron XII Manitoba Dragoons, 3 of the tall Canadian pots can be seen in the image and one of the Coleman 500 stoves (with bright plated tank) can be seen in the foreground.

Once the model was known,* google searches revealed a number of other Canadian war-time produced examples.* Some still associated with the original pot set.
