Vintage Selpac Scuba Backpack and Stainless Steel Tank Band

Description

Selpac brand scuba backpack and stainless steel tank band - no tank.
Backpack is 15 inches tall and 9 inches wide at the widest spot.  Comes with straps but they are short, and a little stiff with age.  Easily replaceable though.  Left side shoulder strap has a velcro quick-release.
Stainless steel tank band fastens with an adjustable stainless steel cam-type lock.  Band has a plastic or rubber liner to protect the tank.
Backpack and band were bought over 40 years ago, used a couple of times, and then put in storage, so they're in exceptionally good condition.  The plastic or rubber around the band is cracking in one place, shown in the photos.  No rust, and almost no dings or marks on the plastic.
