4 vintage Bell System plastic-handled screwdrivers - 3 Stanley/1 Bridgeport

Description

Good morning all. Here is a lot of 4 vintage Bell System, Made in USA, plastic-handled screwdrivers. The tips on the 3 flat-bladed drivers have wear from normal use, but no abuse or re-shaping, and all 3 are perfectly usable if that is your thing. From the top in the first picture:
1. Stanley, Made in USA, Bell System KS-19192 LI hex driver, in very nice condition.
2. Staley U.S.A. Bell System KS 6834 flat blade driver, with the small thin blade that was a Bell System screwdriver standard (enlarged in the 7th picture). The handle is nice, but note that some of the white highlighting the lettering is worn off.
3. Stanley Made in USA Bell System D
flat blade driver
. This one had a life - the handle is dull and has some paint residue, and the shaft at one time had some surface rust. OTOH, the tip is very clean.
4. Bridgeport Bell System E flat blade driver. Nice longer handle.
