Seller: milankey (5,310) 100%, Location: Kent, Ohio, Ships to: US & many other countries, Item: 162141579895 This is a small vintage Yale mortise lock. The backset from center of cylinder to edge of door is 2-1/2". The size of the lock body is 2-3/8" x 3-3/8". The faceplate is 1" x 4". Obviously this is not a full size lock. Found this in a bin in my keyshop. its probably been here since the 1970's. The inside is for a thumbturn (not included). The outside is for a mortise cylinder with the correct cam (not included). The lock works fine. The dollar bill in the photo is not included, it is there to help illustrate the size of the lock.
