The stamped number should be the same as the tag on the tub. You should find the stamped number just in front of the PTO near the clutch pedal. In one of your pictures showing the dash and PTO lever an electrical wire and connection should be laying on the number.
it should say 44?R then 4-5 numbers under them (serial no)
Hope this helps a little!
