Brand(s): Chrystolite

An unusual brand by a company that seems to have made incandescent bulbs, radio tubes, and radiator covers!

Tracing the company has been difficult, and I had to resort to deep searches using the early Indianapolis phone number listed in their advertising, constrained to Indiana, USA. This helped me find the owners placing sale and want ads that otherwise would not have been found. It appears that they began selling Chrystolite Incandescent bulbs, though I have yet to their lamp products in advertising.

Radio tubes sales must not have worked as well as hoped, since we find advertising for a brief one week period in Nov 1924.  

Strangely, in May 1925, an A.E. Weist offers his 284 acre Greencastle, Indiana dairy farm for sale, looking for $12k in Indianapolis equity. Was this a stakeholder raising capital or bailing out debts? We may never know. 

By July 1925, we find solicitation for inventment capital, and the first real place I've seen Chrystolite Incandescent lamps advertised. 

Without this key 'Phone Circle 6399' we wouldnt link these references together. I suspect additional investment funding never came, with the original 'production' of tubes in the low thousands. I cant imagine they made more than 10k, given the lack of them that went into the secondary salvage markets. They may have been 'stamp on demand' with a few thousand printed boxes at the ready. When they didnt sell, they were perhaps sold off unstamped. We can safely call these scarce.

How A.E. Weist connects to Chrystolite isnt clear, but he was answering the same phone number in Indianapolis.


As to the physical manufacturing of these...the elongated envelope glass suggests those made by Munder Electric Co., though it isnt impossible that they purchased envelopes made from a common glass plant supplier. If they indeed made lamps, they would have had the right equipment, mostly.

Unrelated to radio tubes, it looks like a company was spun off to produce covers for in home radiator grills. 


Many years later, in 1927, we find one obscure reference to Chrystolite. 

L.C. Kahle, who before joining the David Grimes Organization, and later the Radio R&R Laboratories, was President and General Manager of the Chrystolite Co., manufacturer of incandescent lamps.
