[TRADE or SELL] Large Restrap Frame bag for a medium one. Will maybe sell.

Bought a large restrap frame bag and it seems like it's too long for the frame I'm using. Looking for a trade for a medium sized one if anybody has one. Long shot I know but worth a try.
Or I can sell it for £40, it's pretty brand new and only fitted once, not used at all. Bought from wiggle last month I think. Could've returned it but completely forgotten about it.

It's this one right here

Have a medium one and looking for a large! Will double check the measurements tomorrow and will pm you. Used my bag twice so basically new.

Lucky! Let me know!

On the slim chance the trade doesn't work out I'll take it off your hands for £40.
