Today I have been reading in the Microsoft digitized book of the University of California's copy of "Shrapnell shell Manufacture" 1915. There a SEMPLE Tracer is noted for US shells. I remember reading the name SEMPLE before in US ordnance publications about fuze design. A search brought up US 2415262 patent of 1941, I assume this is the often mentioned "Semple Plunger". Another search brought up 9 british patents between 1902 and 1917 to John Bonner Semple. I wonder if this is the same John B. Semple as about 35 years lie between the british and the US patents. A question to the fuze buffs out there : Do you know of any other fuze parts that carry the name of Semple, besides the plunger.
