“MUST SELL– 1946 Willy’s Engine SN:638632 W2, in front of serial number is 1-11 and after serial number is N1-CR. We are asking $400.00 obo
It is in running condition except it needs a little work. Needs some hoses and the radiator needs replace(new one sitting there for it) I am selling this for a friend (who has passed away) I don’t know much about it so it is best that you come look at it at the Antique Link store in Silver Springs. It is mounted to a trailer with a large Buss saw setup attached.
It can be towed as is. Trailer has an attached hitch.”
