The Xervac Anti-Baldness Device

This was a pretty expensive gadget. Its price in 1937 (assuming that's the year of the ad in the link) was $179.50, which in 2020 was equivalent to $3,288.16, according to The Inflation Calculator. Also, I did a search for the patent number in the ad, and the result was this image:

Now-a-days several products known as laser caps are claimed to promote re-growth of hair. They seem to range in price from $600 to $3500 depending on the brand and model. I searched for electric treatment for balding, got many hits.

I was wondering if that is the same Crosley Radio Company that manufactures those retro-look record turntables? Those that you find in Walmart and other discount retailers?

KDP It appears to be the same company, if I'm reading their Who We Are page correctly.

The original Crosley Radio Corporation ceased in 1956 except as the listed owner of WLWT-TV (until 1968).

The current Crosley Radio, beginning in 1984, is a marketing scheme, trading on the traditional US Midwest name while buying their products from China. It has none of the corporate genetics of the original, and it's actual name is: Modern Marketing Concepts Inc..

Thanks, Phideaux, for linking to a fascinating article. I particularly like the Icyball refrigerator. It would make a good Mystery Illustration.

@ges -- Thanks, but I found it a little unnerving. There's something about the same company making proximity fuses and midget cars that just doesn't seem right.

With the variety of things he pioneered, I guess we should all feel fortunate he didn't become a mad scientist.

The Icyball would definitely have thrown me. With the chambers connected by tubing, I might have guess it was a valveless pulsejet variant.

The Icyball would have stumped me as a M.I. It still did until I read more about it at Wikipedia.
