Textbook tropical Y-strap marked Franz Brehme, Walsrode

Rare textbook tropical Y-strap in excellent, most likely unissued condition. The Y-strap retains all straps, buckles and hooks you would like to see. The backstrap is a typical example with woven holes for the adjustment stud. The Y-straps are nicely marked Franz Brehme, Walsrode on the leather O-ring cover. Textbook piece that is becoming quite hard to find nowadays!
