Acquired this gem over the weekend as a gift from an 83 year old friend I regularly visit. He has quite a bit of items from his years of service in the railroad world, and many interesting stories and anecdotes about things from the earlier years of railroading. Quite amazing and fully functional. Dated March 5, 1929 on back. 90 years old !! Quite a treasure and honor for me to have received it as most of my switch locks to date are generic plain jane run of the mill types and not anywhere near that old or railroad specific as this one is.
