Hi all again, 9 years of looking and haven't found anything from the 1950's, air brakes twin screw tractor. Lots of tag axle and the occasional air over, 4x2 tractor unit have come up but nothing else. So since time is marching on I'm going to look for a gas powered tractor unit from the early to mid 60's, C80 or M80. There was a stunning orange 409 powered 1962 M80 on Yesterdays Tractor but apart from that anyone come across any in their travels?
