[Hallicrafters] specs on Johnson caps

[WØQFC]

Walt:

In the 40's and 50's EF Johnson, Hammarlund, National, Cardwell, Millen, 
etc., would have ads in QST and essentially a small part of their catalog in 
the advertising section of each ARRL handbook.

The information was at best summary, but it showed their major capacitor 
lineups and common capacities/voltage ratings.

More complete sales-based listings showed up in the 50's Radio Shack, 
Allied, Newark, Burnstein-Applebee's, etc., catalogs.

Many of the above can be found on the web. For example 1951 Radio Shack 
catalog: http://www.radioshackcatalogs.com/catalogs/1951/ pages 130-132 has 
National, Millen, and Cardwell capacitors.

Each company also had 3-hole punched pamphlets with more complete and 
technical listings of their product lines, I had some of these 35 or 40 
years ago, but wow that was a long time ago. I'm sure I don't have them 
anymore.
