This largest size of the L.L. Davis pocket levels is 7 5/8 inches long, including the acorn finial ends. This is the iron body version, unpolished that was originally japanned on the sides and bottom. Most of that japanning is missing. This example is marked with the L.L. Davis L. & T. Co. name on the top plate, and the model number (39). The vial is good, but is likely replaced. One of the small screws on the brass top plate is missing. This is a scarce size of this level. Easily Good.
