HYMAC 580CT RARE!

[hair bear]

Thanks for the ID comfirmation, I'll put the plans for the world cruise on hold.
Interesting that as you say, the 'T' does appear to be in a different font it seems to have faded in the same way as the other lettering. Never mind, not my machine, not my problem.
As I said I've never had much to do with it apart from tracking in some hardcore one afternoon and chucking some scrap tyres around with a grab, but it's still in regular use even though there is no longer a seat in the cab!
