small german OPTIWA DBGM hazard warning triangle

Vintage OPTIWA DBGM hazard warning triangle in used condition. The foldable triangle is stamped on the rear with "OPTIWA 4/7 DBGM K3613". The warning triangle is a little rusty at the edges. The folding mechanism works, but should be oiled. The size of the triangle is 31 x 31 x 31 cm, which is the old small size. The original leather pouch has a damaged button, and on one side, the stitching is compromised for about 4 cm at the top (see image #2). The leather pouch size is about 28 x 16 cm. A made in Germany accessory for VW Oval Bug, Split T1 Bus, Type 3, Karmann Ghia and Porsche.
