Traffic signals are surprisingly easy to buy; I bought two for less than $50 each. Older ones, unless they are some kind of rare variety, are also very easy (and inexpensive) to acquire. Once you have one, it's easy enough to have a lens made (measurements, etc)
I asked a good friend of mine who was an engineer (side rule and compass, not throttle and brake) for the MTA if he had heard of a specific NYY subway signal and he had not. I showed him the pictures of the Craigslist ad and he still was not convinced. Granted, he wasn't alive when these units were purported to be in service, but I'll take his word over some rando selling something on Craigslist.
Just my opinion based on the research I was able to conduct.
