My book isn,t the latest on the HP but it says the D6 was 80 HP at 9U 16,5xx but if I recall the last of the U models were about 90 HP I believe and yours would be in the middle to later 50s before they went out of production as my book only shows starting up year.I have no specs on the weight of it.
I show it as being a 1957 model.
Here are some specs and weights but the hp did grow in the later serial numbers with production ending at 29764 (1959)
Thanks for the quick response, I tried to find a referance guide online but came up blank unless i wanted to buy a guide that gave all the details. Does anyone know it the serial number list that ACMOC sales contains year, weight and engine specs.
Also would $ 5000 be to much to pay for a machine of this year.
