B67-574 GRAVITY INCLINOMETER. Union Gravity Level Co. Patented in 1923 by James Reed and manufactured in several lengths by the Union Gravity company of Des Moines, these were distinguished by their all aluminum construction when aluminum was still a relatively rare and expensive material. This is the 28" version, which we believe was the longest, and in very nice condition. Fine 200-400
