Hi all, My Long term project is a Lister L , Number34113. my question to you is this; crank case breather is mounted on the door does this make it an early or late model? i have no way of telling being as the spec plate is missing ! the flywheels and crank have matching numbers This will also dictate what type of head it should carry being as the original was missing! Normally i would have stripped this one down but being as it came to me from my home village farmstead i have an attachment to it !. regards, Karl.
