How certain are we the alphabetic codes represent dates? Could they represent regions, where development density expanded coincidently with passing decades?
I have never found or seen anything in writing that explains the letter codes. I think most collectors have assumed it was chronological because of the relative age of the things or the tell-tale markings on the things with SYSTEM A, B, C, and D letters. But I suppose anything is possible.
Today's flea market find is a good example.
BELL SYSTEM S first aid kit. That is the latest letter I have ever seen, and almost weirdly late, since I don't recall seeing many if any intervening letters between, say, E, and S. And yet the case seems earlier than the letter might seem to indicate. In fact, if I wasn't aware of SYSTEM A, B, C, and D items, and the implicit chronology of them, I might even think it was "S" for Safety.
But, we have other FAKs on the thread, and they help illustrate how the letter codes seem to be chronological.
See Page 11, Post #424. southalabama posted a BELL SYSTEM C FAK with contents that look exactly like WWII or KW era military FAKs. (In keeping with the general timeline of A and B tools looking prewar.)
See Page 5, Post #174. Old Radar posted a BELL SYSTEM FAK without a letter code, and empty, but the contents decal, though slightly different than mine, is clearly later than the BELL SYSTEM C FAK that southalabama posted. Probably 50s or 60s.
I am guessing late 60's or 70's on mine. I could probably get closer by trying to date the composition of the ointment.
As I said on the Garage Sale thread, it's much later than the rest of the BELL SYSTEM stuff (mainly A and B, some C) in my collection and the BELL SYSTEM B box that I am keeping it in, but it's a metal case with a metal clasp, not plastic, and won't look at all out of place. It's just the kind of accent piece that makes a BELL SYSTEM kit look authentically more complete and better.
It's complete - and the contents were still arranged exactly as the instructions under the lid recommended.
