Ok folks, I have an issue that you need to help me with. The story goes that these came direct from the Louisville plant from an old retired employee. That's all well and good except! There's something just not right here,
;-) The one on the left is the Roth version of IH-369180R1 and the one on the right has a part number of 39169R1. Both look to be NOS, but I can't find anything on the 39169R1 anywhere.
