Radio Electric Supply Co. (RESCO) was THE place for electronics when I was starting out in Radio. They had everything, or could get it quickly for you. This shows them at 961 East Sullivan Street in Kingsport and this is where I remember them. At the station where I worked, it was standard practice to answer any query as to where the engineer was with “You checked RESCO?”
However, in 1945, the company is listed at 210 Cherokee Street (near the alley behind the bank) (across from where Kingsport Camera Shop used to be), you know the place.
This little measuring tape (I haven’t chanced pulling the tape out to see how long it is) was made in Hong Kong. That the trademark is “HONG KONG” and not “Made in Hong Kong” places this in the ’60s.
