Keith didn't work at Ogden after WW2. Or at least long after. I spent an afternoon with him at his shop in Salmon after killing a bear near Shoup early in my hunt. Had a few days to kill and wandered into his shop. He knew some of my realitives here in Idaho, we (my unit) had just done a rescue of a logger near Salmon that had been well publicized.........so the conversation was on, for 4 hrs.I was told it was a project that Elmer Keith worked on in Ogden during the Second World War. We got to see and play with a number of different Toys while I was at APG.
