Another photo of a Thermostart.
As a side issue, from the photo its obvious this is a work tractor, never 'factory rebuilt' in its 25 years. Never needed it, given normal maintenance it still runs like new!/forums/images/graemlins/grin.gif
But this photo compared to Art's illustrates that the nice appearance of the rebuilts is an added value, worth some $, compared to the ragged appearance of old equipment showing its age. If I were in an application where appearance mattered, like a riding stable or something, then a cleaned up unit would have some appeal for me.
