In the last month the plastic headlight bezels on eBay sold for $26 and $134.55 and an aluminum dash (instead of plastic) sold for$143.50, just to give you an idea of the price range. I believe those two pieces are common to the whole line-up, from MF7 to MF16.
One of the members (1971 MASSEY 12) got a mould made to reproduce the plastic nose ring, but I haven't seen him on the board for almost a year. He also got a mould for the steering wheel center piece and olcowhand turns a beautiful polished aluminum center piece as well.
I'm just on the other side of the bridge, if you're over this way.
