In this auction I have 2 Lionel model 4150 transformers gently used.Both of these units I have tested hooking them up to track and powering a locomotive and they both worked. Both as seen in the photo's have blue cases no cracks or damage. Due to the weight of these I will ship USPS medium flat rate box. Thank you for looking at this auction.
