I've recently purchased a used Cobra wing rigger. Though it doesn't seem to fit my Jantar Std 2 wings -- it's certainly made for wider wings. I'd like to offer it for sale and would like to identify its size and which wings it is designed for. All I know is the rigger cuff will go from 30 3/4 inches to 39 inches chord (780mm to 990mm). Please advise.

Thank you,
