B63-577. ADJUSTABLE LEVEL. Shorts Patent. Patented by A.V. Shorts of Allegheny, PA, in 1905, it consists of four level vials mounted in a circular housing adjusted by a worm gear. They were sold as an accessory to be mounted in the level stock of the buyer's choosing and are found in a variety of stocks. This one is super clean, with four unbroken vials, adjustment works smoothly, mounted in a 26" cherry stock with decorative inset panels. Missing a couple of small brass rivets but overall the nicest example we've seen. From the collection of Pat Gefre. Fine 100-200
