Postwar Lionel 3666 Minuteman from the 1964 Sears #9820 military set. This is in excellent condition. The white is slightly yellowed from age. Cannon raises most of the way when roof is opened, but not 100%. Cannon fires, and 4 shells are included. The one operating coupler doesn't spring open on its own when released, it needs to be pulled.  The other coupler is fixed. Please use pictures to verify condition, they are part of the description. Let me know if you have any questions before purchasing, including shipping and packing. Thank you
