19th Century “Cotterills Patent” Door Latch with Security Lock
An unusual early 19th Century bow type door latch in totally original condition. Designed to be worked by a pair of door knobs (https://www.domesticruralantique.co.uk/en-GB/knobs-handles/georgian-brass-cottage-door-knobs-set-a-/prod_10276#.YDPO-4HfWf0) which turn to lift the latch via a 1/4" square spindle.
Two things make this an unusual latch, one being the makers brass label with their name under a Lion and Unicorn, the other being the locking lever seen to lower left.
