My Massey 65 diesel has a 4 letter serial number prefix.
UNDM 704769. 1964 model from tractordata.com
Looking at my parts book doesn't seem to address this 4th letter. All the info I can find only addresses three letter prefix
What is this telling me?
From the the yellow underpaint it seems to have been decided it is a utility chassis. Is this a factor in the 4th letter?
My question is:
What does the UNDM mean?
Where do I find the transmission stamping?
