340120 should be 34012C which is a 3400 (Utility model in the 3000 series) with a diesel engine, live PTO and an 8 speed transmission.

6B21B is the Unit Number (production date code) and it says that it left the assembly line on February 21 1966 during the day shift

C1327726 is the serial number, which is a 1966 serial number and agrees with the Unit Number above.

I am not sure what the C21 after the serial number is, possibly a build code for the transmission.
