Can anyone tell if this is a doubles or singles wing? I got a real good deal on trademe for this bcd (315 NZ dollars) and didn't pay too much attention to what I was buying. However the wing looks massive and I'm thinking it might be a doubles wing? The seller claimed it had a lift capacity of 25kg. I initially thought that they meant lbs and didn't think anymore of it but now that it's arrived I'm wondering. This my first bp/w so I've got no experience with how it should look. For reference the flat area inside the donut is the size of the backplate.
