Thanks Micheal. Wierd seeing the weave going in that direction and that odd-looking right side but if I remember correctly, these were done on a continuous roll so some were offset? Rare triangle that one but you know that already
Agree, the back does not look like the other triangles I own, but the collector where it comes from is absolutely trustworthy and an expert, so no doubts here
The triangles appeared in 1933. Between 1933 and 1936, the manufacturers did a little bit of what they wanted. In 1936, the RZM regulated the manufacture very precisely. Only the font will change in 1938.
Most triangles manufactured between 1933 and 1936 are among the rarest.
"Nord Ostsee" (1933-1934) exists in 3 different "non standard" manufactures ("standard" = 1936-1945). Here are the pictures of these 3 fabrications (To have the exact chronology, picture 2 should be picture 3).
