Seller: mini-horse (178) 100%, Location: Beaverton, Oregon, Ships to: US, Item: 222778516012 Nice vintage antique Yale & Towne heavy cast brass Monolock door set with blank key in excellent period condition. Set appears to be complete (except no mounting screws) with parts moving freely. ** Non keyed knob turns and initiates latchinig action. The keyed knob does not move and appears to be "locked". I believe that the key needs to be cut in order to unlock the set.**. A really beautiful piece of vintage/antique Yale & Towne door hardware. Backplates measure 11" high, are 3 1/2" wide and approximately 1/2 deep. One plate is stamped Yale 3120 RB IN. The other is stamped Yale 3120 IN, 3220 OUT and 3120 RB OUT. Door knobs are 2" in diameter and feature a raised bullseye detail. Door set is about 2 3/4" deep when assembled. I am not an expert on Yale & Towne (or on door sets in general) but would be happy to try and answer any questions or provide more photos in further describing the item. Material: Brass, Featured Refinements: Vintage Door Lock, Color: Aged Brass, Maker: Weiser?
