As far as I can tell, this slot is all original. I don't know about the back lock and key. This was one of the last goosenecks by Mills, and being a PENNY slot is said to be highly collectible.Don't be shy, if you have any questions or want photos or videos, please contact me directly(last photo). Slot pays out and works as it should. A very nice example of a 1cent Silent Gooseneck. Also, have its 5 cent brother if interested in both. GRECO AMUSEMENTS, INC- BADEN, PA.
