YALE & TOWNE Quad M TIME LOCK from Bank Vault - RARE

Description

I am selling this extremely rare Yale & Towne Quad M Time Lock. A description of this device is found on page 294 and 295 of the book American Genius, which is the reference book for bank vault time locks. The four movements are original and numbered consecutively. One movement is not running and will need repairs. The others are all working. Overall, the condition is very good. This lock weighs 23 pounds and is among the largest made. This is a rare opportunity to own one of the very few remaining specimens of this model. It's truly a museum piece! I am starting this auction at a modest level to give all serious collectors a chance to get in on the bidding.
MY BOOK IS NOT INCUDED. I'm just showing the book and a few pages as reference data.
This unit will be professionally packed and shipped by my trusted FedEx shipper.
