I have seen these version "-E" components...I have a couple.

I am not aware *any* difference between them and the "-B" versions.  I've seen mention of only the "BC-456-E" in official documentation (12R2-3SCR274-1 Operating Instructions, 25 JUL 56, IIRC) in a passing reference without any significance or explanation, crudely typed in.

I believe the "-E" marking is specious...most likely an error of some sort where a "-B" should have been.  The -E models are identical to the -B models, from what I know.  But I'd love to find out something different.
