The patent, official datasheet and press release for the GI-10 Inditron are all dated 1954. Here's the original datasheet, dated May 1954... http://www.decadecounter.com/vta/pict5/inditrongi10.jpg The GI-10 patent (US2756366) was filed on April 1, 1954, and the Popular Science press release is dated September 1954. There are also a few patents for Inditron-like devices which predate the Inditron patent. The Inditron is just the first one to make it to production. There are several Haydu-Burroughs ads for both the Nixie and 6700 beam switching tube that are dated from 1955, and I have seen no ads or tubes dating earlier. The very earliest ad states that the 6700 was perfected by Burroughs Research Labs and produced in quantity at the Haydu plant, which was already a subsidiary of Burroughs at that time. All I know about Saul Kuchinsky is his extensive patent history. He was deeply involved in the development of every major class of Burroughs tube.
