Thanks for the input. Yes, I saw the one on eBay, sent a note a few days ago but no response. (The dimensions he has listed are too large for the 22mm pm727).
What's odd is that the flats on my pm727's spindle are HAND GROUND and not machined. The provided wrench was way too sloppy. I did machine a new wrench but like I said, the factory handiwork was a bit "rough".
TIA
Rbt!
