B59-565 GRAVITY INCLINOMETER. Ewing Patent. Patented by Alvan Ewing of Lewisburg, TN, in 1889 and features a weighted pendulum that acts both as level and plumb. All of them are rare, but this is an example of the 12" version; we've seen only one other. Very clean hardwood stock; the pointer is a little short and hard to see in the plumb window but works smoothly. From the collection of Dennis Fisher. Fine 300-600
