Description
This 5-3/8" steel and ivory drawing pen is marked on one side of the pen point: D. R. P. 40967. On the other side, it is marked: BREVETÉES (/) S. G. D. G. These marks mean that the maker had received German and French patents on the pen after Germany established its unified patent law in 1877. Compare to 1978.2110.08 and 1978.2110.09.
The previous owner collected more than 1,200 hand tools and machine tools and displayed them at his family's building company in Baltimore, Md.
