Title Northwestern Mutual Door Knob Display

Description Square wooden display with a gold frame with two Northwestern Mutual door knob sets screwed to it. Wood display has a support piece on the back to keep the frame standing on an angle. Two door knob sets are made of brass. The frame of the two door sets are identical. They both have inscripted "Northwestern Mutual" above the knob, and "Life Insurance Co." below it. They have intricate design patterns all around the rectangular door frame and at the base of the knobs. They both have round knobs. However, one is an internal plain knob with no lock, and the other is the external knob, it is larger and with a different face with two key holes and the word "Yale" on the center. It also has its entire lock set which shows on the left side. On that, it is engraved "Yale Mono Lock" followed by the company's name and patent info.

Summary Very good

Assessor Samanta Pugh

Notes The two door knob sets are in overall very good condition. The incriptions are clear and the brass shows some few dark smudge spots. Among the design patterns some corrosion is seen which shows a light greenish coloration. The internal door knob has some scratches and smudges on and the external knob presents some corrosion around the edges where the key holes are located. The lock piece on the side also presents few scratches and smudges, and the back piece of the lock definetely shows a good amount of corrosion. The wooden frame is in fair condition, the wood base and the frame present scratches. The frame is in worse shape, it has chips pretty much all around and the gold paint is wearing off in several spots. Also, the upper part of the frame is loose. The back of the wood display as well as the support wooden piece also show wear, having scratches and small chips on several spots.
