First pattern hidden stitch Y-strap marked Frost & Jahnel, Breslau 1939

Rare 1939 dated first pattern so-called hidden-stitch Y-straps in very good condition. The Y-straps are complete and the leather is still rather supple as can be seen on the pictures. The Y-strap features typical early aluminium hardware, only the back strap features steel painted hardware. This example is nicely marked Frost & Jahnel, Breslau 1939. Rare and hard to find first pattern example in excellent condition, especially dated 1939. hard to upgrade!
