Listing is for a vintage Adlake solid brass RR Lock with chain. (See photos for condition). Lock will open but internal Spring is weak and the shackle sticks and needs to be pulled open when opener is turned. E-Mail for details. Thanks for looking. Check my other Listings for more RR Items including Reading RR 4-way Switch Lantern, and Vintage RR Signal Lamp and Lantern Co. P&R Ry Lanterns. E-mail with any questions.
