For lovers of historical diving equipment:
I sell my first buoyancy aid, a Sailor Sub Buoyancy Vest, newly bought in 1992 (!)
The good piece seems to be even tight after a provisional test with rinsing water in a tub. The valves also work. Nevertheless, I sell the vest as a decoration / exhibition item without warranty / warranty.
Update: The vest has been inflated in the corner for 48 hours and is as plump as at the beginning. Seems to be still dense.
The emergency bottle (0.5l) is no longer available. The connection is closed with a blind plug. On the back, in the area of the buoyancy bottle holder, my name with Edding is attached. But that's pretty faded over the years.
30 Euro plus shipping
