I've come into possession of a couple of documents, not sure whether I have these already: 1. BC-946-B Instructions (Jan 7, 1943, 14pp) 2. Handbook of Instructions, Radio Set SCR-274-N (rev 1 Oct 1945, 206pp) If for some reason these are not in the general pool, I would be happy to lend them to anyone who would copy, publish, and return them. 73, ian K3IMW
