Fig. 2. Mossberg Model C Bicycle Wrench, with Insets for Side View and Marking Detail, ca. 1902+.
Fig. 2 shows a somewhat later Mossberg "C" bicycle wrench, stamped "Mossberg Wrench Co." and "Central Falls, R.I. U.S.A", with "Pat. Nov. 19 & Dec. 31, '95" on the lower line.
The overall length is 5.1 inches. The finish shows traces of nickel plating, although most has been lost due to wear and rust.
The first patent date refers to patent #550,025 filed by Frank Mossberg in 1894. The patent describes an adjustable wrench with a thin profile made possible by the laminated steel construction.
The later date refers to patent #552,325, filed by Frank Mossberg in 1895.
The location marking in Central Falls indicates production after the company's 1902 move from its original Attleboro location.
