Sorry to see that this one is up for sale. If it were me, and I think I'm fairly sane, you see Paces and Zaskars frequently up for sale, but I've never seen a McMahon for sale or in the flesh, so I'd keep the rarer of the lot, the McMahon.
I can't believe that no one is buying your Zaskar, its a bargain at the price you are selling it for!
