Seller: riner10 (653) 100%, Location: Sandersville, Georgia, Ships to: US & many other countries, Item: 322342225437 Up for sale is a Knobby-Lock door lock sample that is mounted to a wood housing and base that is black in color. This is a very unique and rare style of lock. This lock was used as a counter working display to demonstrate how the lock operated. When the lock cylinder, which is mounted in the side or edge of the door knob, is turned to the locked position with key, the knob free wheels and is then disengaged from the lock plunger. This collectable could be at least 50 years old as it came out of an old hardware store from the 1960's. There appears to be no damage and the lock operates. It needs a good cleaning and the lock finish and black paint on the lock display has faded. The display unit measures: 4.25" x 6" x 5" tall. Thanks for viewing!
