This thing says it was copyrighted in 1968 but it sure looks older than that. I guess it has aged, just like the rest of us. This wheel is 5.5 inches across and in stained shape. But it's perfectly usable. The Penny Saver side (it has a penny on it!) helps the homemaker determine, for example, how much per ounce she's paying when she spends 50 cents for 4 pounds of lard. If she needs to buy 10 pounds of lard but only knows the price for the 4 pounds, then this wheel helps her figure that out, too. What a lifesaver!

On the other side we have the Cook-Aid, with an oh-so-charming little drawing of an old-fashioned cast iron stove. On this side of the wheel, one can learn how to double a recipe or change the proportions to something else. You can see that this specimen has been stained with something. It looks like grease to me.

All in all, this is a great little wheel for those of us who don't do math.

This must have been a bank giveaway. You can bank on the "Wales"! A wheel is much better than a toaster, in my opinion. This wheel measures 9 inches across and is in fair shape. I'll admit: it's not the most attractive item in our collection, but I've seen worse.

Each country has been assigned a different native animal to represent it. The other usual stuff is here: capital, languages, major products. Pakistan barely makes the map. That's a far stretch to be considered a "near neighbor" of Australia, don't you think?

A Rita Todd inscribed her name on the back -- twice -- along with her address in a Sydney suburb.

Here is your guide to drug abuse. They're all here: mescaline, pentobarbital, cocaine, marihuana [sic]. The information includes slang names, which is my favorite part. I like it that slang terms for alcohol are included, just in case you didn't know what "booze" is. I also like it that amphetamines are sometimes referred to as "co-pilots".

This garish, almost psychedelic wheel is 8 inches across and in good shape. The 1969 copyright belongs to Spenco Corp. of Waco, which now produces insoles, shoes and foot care products. Perhaps they gave up on the War on Drugs. One assumes that Dr. W. R. Spence is the "Spenc" of Spenco.

Here are the ABCs of industrial maintenance! This wheel assists the toolist in selecting the appropriate attachment needed for the job. Enerpac offered attachments for your chain plate setup, your toe lift ram setup and even your duck bill spreader setup!

This wheel measures 6.5 inches and is in pretty decent shape. And wouldn't you know it? It's another quality wheel from the folks at Perrygraf Corp. The copyright date indicated is 1961, an excellent year.

Those were days of classic company names: Applied Power Industries, Inc., Automotive Distributors Inc., Industrial Distributors Co.

If you need to order yourself some Miller Fluid Power stock cylinders, you'll want to have this chart. This thing measures 8.75 by 11.25 inches and is in fine shape. The copyright date is 1973. The Miller logo suspiciously (or not?) resembles the Miller beer logo. Both companies involve manufacturer of cylinders.

I wondered what would happen if you managed to remove the inner sliding card and reverse it. When I did so, I noted that someone named Chuck Long has inscribed his name to both sides of the card.

This little 4-inch wheel converts pounds of shelled corn to bushels. I don't know how moisture content is figured.

There is no date on this one. It's in decent shape, being made of a sturdy, coated cardboard. Pfister Associated Growers may or may not still be around. The record in their home state seems to indicate it's dead. Poor Pfister.

I'm afraid this is going to be on of those "I don't know what this is" wheels. I get what they're getting at. Let me try to explain. This chart automatically presents the wavelengths of the main absorption bands of 61 classes of chemical compounds. By setting the cursor to a given wavelength this chart automatically identifies most of those commonly occurring compounds producing absorption bands at that wavelength.

This wheel is 7 inches across and 8.5 inches high. The copyright date is 1965. The "Wavelength to Compound" side sports a shield of plastic on the disk.

​I like the blurb about Barnes on the one side. "Our products are good." Well, you have ME convinced.

Don't fight it. Burn it!

Here's a little wheel of dinosaurs produced, I guess, for or by Golden Records. This is 5.5 inches square, not including the fearsome, yellow TRex head. It's in excellent shape. It has good ol' Triceratops, my favorite!

There is no date on this one but it's obviously not very old at all.
