Reversible winter parka suspenders

Reversible winter parka suspenders in very good condition. Both straps have never been sewn together. I believe this is the first pattern removable example. The first pattern straps do not cross and are sewn directly to the garment. This is a removable set but they do not have the stitching attatching both pieces to each other which probably is the pattern after this one. Hard to find spare pieces!
