Cornell-Dubilier Capacitor Ad: 2017 or 1947?

After looking at so many vintage electronics magazines, the differences in form factors of resistors, capacitors, inductors, amplifiers, and even hookup wire between then and now is very apparent. Physical sizes have shrunken significantly, and the packaging materials are noticeably more refined today. There were no surface mount devices, and nearly all components had either long leads for wrapping and soldering to posts or lugs, or they had lugs or posts to which said components leads - or hookup wire - was attached.

Seeing this canned capacitor advertisement from Cornell Dubilier in NASA Tech Briefs, made me do a double-take since it is reminiscent of capacitor packages of yore. For that matter, it could be a plug-in quartz crystal from a mid-last-century vacuum tube radio set. Of course the pilot's flight suit and airplane in the background confirm a present-day vintage.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
