Well tinplate fans I cannot come up with anything close to the postings of Fatman today, but I am going back to a subject that I posted on before...signals. Today, I have two Marx No. 312 Manual Semaphore's. These boys are right out of the F.W.Woolworth "Timely Table of Railroad Accessories" from 1938. This store catalog covered most of the Marx line including trains and accessories. The price of this semaphore in 1938 was $0.10 or 10 cents. It is all sheet steel (no plastic) and is operated via a link from the base. It stands about 7" high from base to tip. Not too realistic I suppose but I love the "pre-war" look of them and the Marx simplicity.
One nice thing, this was taken with my new phone camera and it is a much more clear picture than my old phone camera, so I suppose that is an improvement. My photo skills started when I earned my Boy Scout merit badge with my Kodak Brownie, 620 film camera in about 1953...have not improved much since. 
Best Wishes
Don
