This is the Pyro Motorized Fishing Trawler Model Kit, manufactured somewhere in the 1950s to the 1960s. It is the "Marilyn M", Pyro model number 251. It appears to be in excellent original condition. The three piece hull and deck sections are complete and unbroken. All the remaining parts are still in the factory sealed bags. The battery powered motor appears complete and is packed in its original box, which is in excellent condition with no damage and is solid. It has not been tested. All of the original paper (the four page instruction sheet and two additional smaller inserts) for this model appears to be included and they are untorn and complete. The box itself is in excellent original condition, and with the exception of a slight blemish in the lower left corner, is solid and is a brick! Note: I have no working knowledge of the Pyro Plastics line of products, save for the fact that they were the manufacturer of model cars and military trucks for Lionel Trains. What I have listed above is all that I know of this item. It is sold as is.
