The plethora of markings on WW2 German military equipment may not be to everyone's interest. However, we would like to share our particular interest in the marks found on items of bakelite equipment. We have combined just some of them above; found on losantine tablet tubes, a protection against blister gas attacks. These would hold around 12 tablets. Also shown are a bakelite binocular case, fuze caps, tropical water bottle cup, field telephones, fat containers etc. The markings on most pre-war items are easily identified as makers logos. However the German military, perhaps thinking ahead realised that such logos could easily provide enemy intelligence with potential targets for bombing. It was the German Federation of Electrical Engineers who first attempted to present guidelines for material classification in 1924, as many of their members were involved in the process of bakelite production. The national material proofing house (materialprüfungsamt), based in Berlin Dahlem to come up with the solution. In December 1938 the "MP" devised the common logo, around which information on the maker of the item, as well as the chemical composition of the bakelite could easily be displayed. Examples of which are to be seen above and below. The triangular logo in the centre is BEBRIT, Preßstoffwerke GmbH, Bebra und C.F. Schlothauer, Ruhla. They produced "Type S" bakelite, both maker logo and adjacent MP code appeared together. We have analysed the logo as well as the codes and provided a list of makers as well as chemical composition of the bakelite below.
Below: is an example of the Materialprüfungsamt logo. We have "broken down" the logo to make it easier to see the component parts. Below the example is shown how it was incorporated in designs. You can see here that it was often used as well as the firms logo.
