Thankyou Dennis. Yes I did indeed find myself on Tony¡¯s website. I¡¯m at the level where differences are being talked about but I¡¯m not seeing the physical differences. Wood from the trees! ?I don¡¯t even know what model is truth be told. Stage one will be a ruddy good clean up and see what¡¯s what. Blatantly chipped teeth on one of the big cogs near the chuck, and reading site looks like parts have to be hand made. Such pretty machines.?
