My
stockpile of over 120 original wooden "Z" knobs
(plus there are hundreds of more original knobs on my
actual radios). These knobs fit sets from 1936-1938. Zenith
introduced the embossed "Z" or "lightning
bolt" knobs with their 1936 model line-up. Unfortunately,
in 1939 Zenith started using plastic knobs on new 1939
models. Some 1939 radios did continue to use the
wooden knobs and were primarily electronically feature-modified
chassis in carry-over cabinets from the 1938 line-up. Such
models include: 9-S-365, 6-S-362, 6-S-361,
6-S-341, 6-S-330, 7-J-259, 6-J-257, 5-J-255, 5-J-247,
7-J-232, 6-J-230, 5-F-251, 5-F-233, 4-F-227, 5-X-274,
5-X-248, 5-X-230. Some sets, 200-series farm radios,
were completely unchanged from the previous year and
still carried the 1938 model number. Many people
have speculated about the manufacturing process Zenith
used to emboss the wooden knobs. They apparently used
a metal stamping die with hot water or steam to soften
the wood and create the raised designs on the knobs. Sorry,
none of these knobs are for sale. Original "Z" knobs
do show up for auction on Ebay or amazing reproductions
are available from www.antiqueradioknobs.com. |
