I've seen other people put old photos on Facebook for a throwback Thursday. Attached is a photo of me (right side) and my HO layout in 1951. Notice the paint job on my passenger train and F locomotives and the print on the wall. How about the volt meter at the bottom, just right of center. I still have my Monon F3A, it has a heavy metal shell.
Now all my Monon locomotives and rolling stock are N scale.
