B66-563 LEVEL WITH ORIGINAL LABEL. Webb Patent. Edward Webb of Fitchburg, MA, received an 1886 patent for a cast iron level with the level and two plumb vials enclosed in a central compartment with an elliptical access plate. The majority of known examples are completely unmarked, but a few are known with the name of Fitchburg Level Co., which manufactured the levels, cast into the cover plate. See Rosebrook, page 112. The rarest form have green paper labels on the cover plates, with "Empire Spirit Level" and "Greene, Tweed & Co., NY" printed on them. These were probably also manufactured by Fitchburg and sold by New York hardware company Greene, Tweed. The rarity of this version may be attributable in part to the fact that the label covers the screw that had to be removed to replace the vials. These vials are 99% complete and very clear. The label on the reverse side reads "Patent No. 354,056" which is a typo; the actual patent number is 354,076. All vials intact, japanning complete, the nicest example we've seen. Fine 300-600
