Many thanks everyone for your useful observations.
When I first posted the question I had just pulled a piston and just wondered what type it was and whether spares were even available. At that point I had not had the chance to measure for wear.
Well things have moved on now and the bore measures 4 thou oversize. At the same time I crack tested the 1 1/8" crank and as the saying goes "it is when it will break, not if it will break", judging from the photo below, very soon.
So all in all I thing I will do the full job, new crank, re-metalled rods. re-bore and new pistons. should see me out!
Thanks again for your input.
