Here I have 3 Marx postwar #709 50-Watt O gauge AC transformers. The top 2 have been tested and kinda work; they provide enough power at full throttle to barely move a small to midsized locomotive, while the bottom 1 is untested as its power cable is heavily deteriorated and as a result it's unsafe to use, and I strongly recommend replacing said cable before attempting to use it. Asking $15 each for the semi-functional 2 and $5 for the untested and unsafe one
