Ha Ha, The world has really gotten small! He's the chap I was referring to:). He found the shaft seals but neither he nor I have been able to locate anything that gave the part number for the ring so he was unable to check and see if he had one. I guess he must be on this forum too? I found him on hobbytalk. He had suggested I try a couple of other sites where collectors hang out. Hadn't had any luck until now. Seems a lot of people kind of frown on these little Macs.
Cheers,
Kevin
