Up for auction is this nice brass PRR MPD (Pennsylvania Railroad Motive Power Division) 3 1/2" padlock. I purchased a large lot of these nice padlocks at a recent auction here in southern Ohio. I have them up for auction or will soon have them up for auction as well. Please email with any questions and thanks for looking.
