Wynn’s Friction Proofing

Yet another SoCal entrepeneur starting in his garage. Image and text from .

This is a heckuva story although most of it occurs after 1939. Click on the link to learn more.

“Chestien Wynn, a 70 year old retired attorney with an interest in lubrication chemistry, discovered a formula he named ‘Wynn’s Friction Proofing’ Oil. This surface treatment for metal actually changed the chemistry of the metal, making it softer and better able to withstand friction and wear.

“Chestien Wynn would mix a batch of his product in his one car garage workshop, fill and label glass bottles with it and sell them to the local service stations and garages. Motorists, who used the products once, wanted another bottle of it.”

Abie’s 1939 Mercury

Your blogger will go out on a limb and presume that these photos were taken in southern California in 1939. The car has a license plate and aftermarket “flipper” hubcaps so it isn’t brand new from the dealer in these shots but I’d like to believe that the photos were taken within a few weeks of taking delivery. Owning a convertible Mercury was a pretty spiffy way for a young man to show the world that he was doing well. Did he also own the boarding house or was he renting a room there so he could afford the car? We’ll probably never know.

’39 De Soto at Carthay Circle movie premiere…maybe…um, no

“I don’t think they actually shot this at Carthay Circle – that tented walkway was much longer and I doubt that neon sign was green and pink, but for the uninitiated, it certainly looks like the real thing.”

Martin Turnbull, expert on the golden age of Hollywood, posted this on his facebook page (link is below). He has written some excellent historical fiction novels about this time and has a lot of interesting posts on his page.

Keystone Cops in 1939 film


Image: photographer/source not identified, probably was a studio promotional photo

In what is probably a publicity still for the Hollywood Cavalcade movie, the Keystone Cops emerge from between two trolley cars in a “tight squeeze” auto that has been specially modified. Most likely, the movie showed them riding on a full-width car as they approached the trolleys then switched to this one as they departed. After editing, it would look like their car had been squeezed between the trolleys. The trolleys are from the Los Angeles Railway and the location may have be on 2nd St. near the Subway Terminal.

Aug. 10, 2020 update: […location] was on Douglas Street at Ridge Way about a block north of Edgeware Road in Los Angeles.*

Normally you wouldn’t find the silent-era Keystone Cops appearing in a movie as late as 1939 but Hollywood Cavalcade depicts the transition time from silent to “talkie” films. Learn more about the film at .

“The Keystone Cops (often spelled “Keystone Kops”) are fictional, humorously incompetent policemen featured in silent film slapstick comedies produced by Mack Sennett for his Keystone Film Company between 1912 and 1917.” Excerpt from . See the link to learn more about them.

On this day in 1939, this photo was approved by the Advertising Advisory Council. The full name was Advertising Advisory Council of the Motion Picture Producers and Distributors of America, Inc. that decreed that “only such advertising or publicity material or trailers, approved by such Council shall be used in advertising and exploiting” a movie that had been approved for release. This was part of the movie industry’s self-policing practices in response to pressure from some members of the public and governments regarding the moral content of films.

* Thanks to the Ralph Cantos update here: that shows a different pose of the Keystone Cops at the same location. Thanks, too, to John Bengtson of for his assistance in providing similar photos, one of which showed a street sign that wasn’t visible in other pictures. And thanks to Steve Crise, Los Angeles trolley historian and co-author of this “then and now” book on PE red cars who may use this blog photo in his upcoming “then and now” book on Los Angeles Railway cars.
