Up for bids is an old prewar Marklin steam engine dynamo lighted accessory board. This board has not been tested for operation but there are not many of these out there. From research it appears that you would have hooked wires from the steam engine dynamo and hooked it up to the back of this board and you could have switched on the lights on the board. Again its not been tested and the middle part of the board itself is warped from heat over the years. On the b...ack one of the terminal knobs are missing. There is a simulated tin faced clock for looks on the board and around the circle of the clock that framework has started to pull away but its still intact. Please see all pics and its a neat old toy and its sold as is where is and its untested. This item is up for bids as is where is with no returns or refunds. I only accept pay-pal and I only ship in the USA. I also package well and I use computer generated labels with tracking #'s on all my packaging. Please also see my other listings for more train items. Thank You!! Ebay has recently upped it's standards for selling in regards to feedback ratings.
