How do you classify these as 5 types? I know there were changes throughout production (especially chains and oilers) but I thought they were all RG34. There are 2 types of cans as well but it has to do with the factories that made them?
Maybe it's a little bit confusing.
I categorise them in 3 major parts according to their year of fabrication ( and so with their different made contents)
I'm now explaining it just for the cans
- the prewar version is made of tinned steel.
In the prewar manufactured kits the metal case was made from "Weißblech" or tinplate. Tinplate is a thin sheet of cold rolled steel, whose surface is coated with tin, getting a relatively good corrosion resistence. From circa 1939 to the end of the war, the tinning was deleted and the case was paint finished. This was the most significant change in their manufacture. Another external change, circa 1940 onwards, was the use of steel latches instead of the brass ones.
- the early and mid-war types are painted. But here we have 3 different models of the cans
From 1940 two firms (Hawig and Mundlos) incorporated in their manufactured cases reinforcing lateral grooves for to fix the internal metal sheets to the case. The most significant change on these grooves was that from early 1942 onwards the horizontal long groove was stamped cutted in two lines forming a long "I" and a small "L".
- the late war cans which is the same as the common mid-war types
And if we take a closer look at the inside whe also can see the different methods of attaching the pin of the latch to the can.
The whole serie of RG34 is worth it to study.
Later on i"ll explain everything with text and photo's of my collection.
