Believe me...it about drove me nuts looking for the sn.# when I found the tractor...scraped paint everywhere...thought it might have even been stolen. Someone on this site told me to check next to the brake cover...and there it was #615. This tractor rolled off the assembly line within the first couple of weeks of production. Someone must have decided to change the stamp location very shortly after this one because a friend of mine also has an early 1948 WD and the numbers are in the traditional spot. This makes the tractor rare but how rare?
Thanks for the response,
