This one is a recent estate purchase. Fresh original survivors in clean condition........... . ..................This lot includes Lionel Vintage Original 2353T F3 Dummy A Unit with horn. Has original box with insert liner. Box has some minor flap issues. The 2353 Santa Fe has horn in the dummy unit. This unit appears to have never been on a track. ( no signs of wear on rollers or wheels.)This most likely has sat in the box for 71 years and never run.  I jump tested the horn (I did not place it on track) and got it to work intermittently. I am sure that due to the fact that this has been idle for so many years that the contacts on the relay and horn bracket need cleaning. There is absolutely no battery leak at all and the inside of this unit looks like it just came out of the factory. There are some very few minor marks on the body which I would surmise are from box marks. Again this most likely sat in the box for 73 years and probably removed on a few occasions and that is why I hesitate to use the word mint. Although I consider this mint, that is a very subjective consideration to some. It is however the finest one we have had in our 65 years of collection trains.
