Charles Guillaume Bormann (1796-1873) was the inventor of the Bormann Fuse, which was adopted by the Belgium army in 1835 and remained a military secret until offered to and tested by the U.S. military in 1851. It became the official time fuse for smoothbore artillery. With original envelop. We could locate no other copies of this manuscript in OCLC, COPAC, or other European Libraries.
