Judging by some of the letters
written to magazines by their readers, obtaining parts referenced in many construction
articles proved difficult or impossible to procure. Ziff-Davis, a major publisher
in 1940 as well as today, ran this notice in a 1940 issue of its Radio News
magazine offering advice as to how one might go about getting everything needed.
Unlike nowadays where nearly every available source worldwide can be found on the
World Wide Web, back then searching could be - and too often was - a long, slow
process. Just finding a phone number or mailing address for a potential supplier
presented a major obstacle to anyone without a collection of catalogs and magazines
- or at least knowing someone who did. Imagine needing ten non-standard parts and
having to write letters to manufacturers and/or distributors trying to located critical
components. The back-and-forth with postal mail could require weeks or even months.
One notable omission from the list is to contact a local amateur radio club for
assistance, where there is a chance one of the member might have the part you want,
or at lease know of a good way to find it - possibly via wireless communications.
