To complete your case of 12 rations (36 units) I have reproduced the box that is made of solid fiberboard. The label design is of a generic style that was used from late 1942 onwards.
The solid cardboard used is 2.5 millimeter thick and is of heavy quality. It is, however, not wheatherproof like the originals. A light coat with a clear matt varnish might make the box water resistant and more durable. This box can probably be used several times.
This box is printed and cut out mechanically and is then creased by hand using a machine specially designed by me. This gives the solid fiberboard its pronounced ridges on which to fold, just like the original ones. The corner is secured with metal staples.
This box was tried fitting in several original wooden cases and did fit some (even with room to spare) but didn’t fit others due to dimensional differences of the original wooden cases. The best but tight fit was in a case with inside dimensions of 20.5 x 12 x 7.5 inch (approx. 52 x 30.5 x 19 cm).
You can make a wooden case slightly larger then the above mentioned dimensions, just 3 to 5 millimeters larger to be safe. However, before making the wooden case, I would recommend first to finish the K Ration units and placing these in the solid fiberboard box, then check the outer dimensions of the complete box.
I don’t make the wooden cases.
