What size OMS wing do I have?

[Contactamer]

Hi all,
So I bought a second hand OMS backplate with harness and wing recently. It’s a red Deep Ocean wing but I have no idea what the capacity/lift on the wing is. Any advice on how I could figure this out? Is there a model/part number tucked away somewhere that I can lookup to figure out the lift/volume?

Thanks in advance!

Fill it with water, then weigh it.

Can you post a picture? There should be a label. 45-60# lift
