Thanks Dave and Herm for the advice. Just for the hell of it I squirted some 50/50 solution of ATF and acetone into #3, let it sit for a while, went for a drive and rechecked the compression. Predictably no change other than the smoke killed all of the mosquitoes in the vicinity!!
I will remove the head, drop the pan, remove the piston and fix it properly as you have suggested.
