Hi, I received an email with comments on these very similar Picnic stoves from my good friend Bryan Miller: "There is nothing mysterious about the Veritas, Thermidor and RM 1 pint stoves because they are the same stove. The only difference between them is that Thermidor always used their unique tank lid on their brand of stove. Thermidor bought RM in 1952 but both factories continued in operation after the purchase and RM appeared to do its own thing although some of the designs were shared by the two companies. Veritas was the brand name of a range of hardware products. The brand name was used by Falk Stadelmann I think. They had a warehouse but no factory. Someone made their products probably to their specification and put their brand name and trademark on them. The trademark was registered but the brand name was used by several firms producing different products. Either Thermidor or more probably RM made the Veritas stoves. There is an oddity in the situation in that Veritas had an earlier version of the same stove and I have never seen a matching RM or Thermidor stove. I am fairly certain that the information about RM being bought by Thermidor is on the website. [ Note RM Engineering was taken over by.Samuel Heath and Sons (Thermidor) in the early1950s ] The lithographed tins were used for the three stoves at one time. The only differences between the different brands was the brand name on the tins and each brand had its own colour tin. Later on the imprinted lettering was dropped from the tanks and transfers were used to identify the brand of the stove. Even later the tanks were lacquered and the transfers were put on top of the lacquer. I suspect that Thermidor were the only factory making stoves at that time and they had a stock of assembled stoves. When they got an order for a brand of stove they simply put the correct transfer on the stoves. This saved a lot of multiple stocking of the same product. SH &S (Thermidor) diversified and made Britool tools which were quality products. They also made brass door furniture. I think that they are now part of the Draper industries" Bryan really is very knowledgable about stoves. Best Regards, Kerophile
The boxes Bryan refers to are not the type used with your stove.
However,I have seen similar stove boxes to yours, used for Veritas and Thermidor stove. These are probably some of the best stove boxes made as they used heavier gauge tin-plate and resist rust better than most.
These boxes came in two sizes, the smaller intended for 1-pint stoves, and the larger for 1.75/2 pint collapsible stoves. It may be that your box is the larger size one.
RM stove are well-made and generally perform well.
Best Regards,
