Antique Arts & Crafts Brass Copper Door Handle Mortise Lock Set Key Entry 6 Side. Hello we have a stunning arts and crafts door handle and lock set. This is a heavy duty lock set. It has a spot for a key. We do not have the key. The door handle has six sides to it. It appears to be in working condition. We are unsure of the material. It is not magnetic so we believe it is made of brass or copper or both, and could possibly have some bronze in it. There is a patent date on the lock set see pictures. The last date patent date is 1900. This is probably 120+ years old. Check pictures for sizes and condition. Selling as is as found condition. If you have any questions, please email. Thanks for looking.
