I've never heard of this before.... but the war effort also focused on the need for 600,000 typewriters for all the communications to and from everywhere

Taking time off between the shooting of scenes at the RKO Studios in Hollywood, Miss O'Hara helped to collect more than 70 typewriters for use by the Army, Navy, and Marines.

Uncle Sam needed 600,000 typewriters for the armed services and contacted all possible typewriter users to urge them to release "1 out of every 4" typewriters for Army or Navy services.

Detroit Auto Graveyards, scrap metal drive, and the scrap rubber drive 1942.

Automobile production became the leading industry of Detroit and Michigan, and by 1920, Detroit had boomed to become the fourth-largest city in the U.S.

At the same time, the dominant auto industry helped advance the formation of another industry that continues to thrive today, one that’s created more than 500,000 jobs across the nation: the scrap metal recycling industry.

As a rising amount of scrap was being generated at the state’s manufacturing and production plants, recycling firms began to proliferate as it became clear that scrap still had value, including when automobiles had outlived their usefulness.

Just as auto assembly lines produce a certain amount of scrap metal that doesn’t get used and can be discarded, scrap recyclers have demonstrated that there’s still plenty of value and use for it.

And since industrial scrap metal recycling helps manufacturers hold down costs, demand for recycled metals has been on the rise for years.

By World War 2, the ability of Michigan’s Auto Industry to effectively handle mass production was used toward the war effort, as workers delivered Jeeps, tanks, planes and guns by the thousands.

(not very informative, and it's repetitious, but, that's a recycling yard from 1942, and this is the text that accompanied it, editted down for brevity)

unexpected consequence of WW2 scrap metal drive just realized...

Union Pacific no longer has tracks near Promontory Summit to celebrate the anniversary of the Golden Spike event.

 They were removed to support the scrap metal projects during World War II.

WW2's changes upon Detroit's normal day to day business

Scrap drives to destroy the cars and trucks and use the steel for making war materials

GM's body making company Fisher Body was making huge anti-aircraft guns, the U.S. Army’s new powerful Stratosphere guns

the discarding of Lancasters and other Canadian Military airplanes after VE day

On September 24 the squadron took off for the final leg of its trip. Destination was Pearce, Alberta, from where the Lancasters were to be sold off or destroyed. This leg has been described by one participant as 'how World War II came to the Prairies.' Once out of Winnipeg, the gaggle of Lancasters set about terrorizing the countryside between there and Pearce. Aircraft, even as big as they were, flew under telegraph wires; one, flew so low it over a farm, it collided with a barnyard duck. Another pilot buzzed a train and recalls his last impression as seeing the startled look of disbelief on the engineer's face as he pulled down his blind!"

On arrival at their final destination, the planes were sold for scrap, although some were also burned on site. Trainers were offered in flyable condition. $800 would buy you a Cornell or a Crane. For $900 you could walk away with a Harvard. Anson V's sold for $5000, and a Canso (PBY Catalina to Americans) commanded $25,000.

'Barnyard bombers' were well worth the fifty dollars asking price. To begin with, a farmer could count on recouping his investment by simply draining gas and antifreeze from his plane. Tires were just fine for a farm wagon. A tailwheel fit the wheelbarrow.

 For years to come the carcass would be a veritable hardware store of nuts and bolts, piping and wiring. In the meantime it made a suitable chicken coop for storage shed. One farmer converted the nose of his Anson into a snowmobile. Bit Waco gliders were hauled away just for their packing cases.

scrap drive for the war effort and the amusement park junkyard

pedal cars in a WW2 scrap metal drive.

WW2 was instrumental in changing the American culture in so many ways, but did you ever hear of car bumpers being donated to the scrap drives?

Rita Hayworth did her part... so if you come across her big old car with no bumpers, now you'll know what happened to them.
http://www.sptimes.com/2005/08/28/Worldwarii/War_changes_fashion.shtml

For an example of immense largese in donating to the scrap drives, read about Panmsy Yount's 1933 Duesenberg Model J Judkins Berline that was turned over to the war effort for it's use as metal for armor plate, or whatever they did with all that steel http://justacarguy.blogspot.com/2008/08/ive-posted-before-about-ww2-scrap.html

Rita was so good looking, the richest man in the world Prince Ali Khan gave her a Ghia bodied 1953 Cadillac series 62

I've posted before about the WW2 scrap drives in the US to get more metal to make into planes, tanks, etc... some stuff donated was rare cars

1933 Duesenberg Model J Judkins Berline, one of two made of this body type. This car was purchased new by Frank Yount at the 1933 Chicago Auto Show for his wife Pansy. She donated the car to a WWII scrap drive http://forums.aaca.org/ubbthreads.php/ubb/showflat/Number/531052/gonew/1/1933_Duesenberg_on_the_Scale#UNREAD
Thousands of average-income Americans across the nation reached into their china closets and donated family heirlooms made from metal to the WW II scrap drive as a sign of making a sacrifice. Families looked out their window and saw their second-hand automobiles that were not junk and still capable of providing transportation to their owners. Even though gasoline and tires were rationed, these vehicles were not totally worthless to their owners, yet they were donated to the scrap drive. The scrap drive was more than just a "junk" drive. People gave up items that had sentimental, utilitarian and monetary value. Sacrifices were made.Pansy Yount was the scion to the fortune left to her by her husband whom she deeply admired and respected. Pansy's social status as one of the wealthiest women in the world at that time required she do things in-line of what was expected of her in consideration of her social status. Pansy's desire to contribute to the war effort by participating in the scrap drive required she donate metal representative of value to the donor. For Pansy to collect junk in order to find somthing to contribute to the scrap drive would be considered below her dignity, besides, rich people don't keep junk. In order for Pansy to contribute to the scrap drive with some semblance of making a sacrifice, she would have to donate something representative of value - something like a Duesenberg. And she did. When she found the car got picked up by someone for their own edification she put a stop to that. Her car was going to be processed the same as everyone else's. Pansy had the money to afford whatever she wanted, and that Duesenberg was a symbol of what a person of her stature would contribute to the scrap drive.
