Chris,
I am looking at a Cockshutt RC 1950T row crop. It has 55 series rear wheels on there... can this be right? Codes are G 77, H 38, I 88. It is built on 4/29/68. Would this be late enough to have 55 series wheels?
There are also a few codes I cant figure: Style A 480, Y 623 and W 563.
 
One thing that's odd is that there is no bypass oil filter. Ever see one w/o it? It is the correct engine block per build card. I am trying to figure why someone would take it off.
