Original 1943 electrical trade vintage ad for JAMES G BIDDLE COMPANY.  Main office and plant was located at 1211-13 Arch Street, Philadelphia, PA.for

Manufacturers of Megger Testers.

To Our Customers and Friends:

Megger Testers are, as you can well imagine, in unusually heavy demand during these strenuous days. Now, if ever, electrical equipment must not fail.  Although the demand has been for a quantity of instruments many times larger than our normal pre-war volume, we have so far been able to fill most high priority orders on schedule. 

Unbound from a 1943 electrical engineering magazine, this unique old one-page advertisement would display beautifully matted and framed. Nice graphics. World War 2 propaganda. A fabulous addition to your retro electrical library.
