Yes, I double-checked, I got the manufacturer right this time.  Probably from the '50s, when "magnum" shotshells were "new."  I like the caution about shooting them only in guns in good condition.  I wonder how many 50-year-old shotguns were damaged by these, back then (if any).

And for all you Hank Hills out there, here's the backside:


Do these look pinkish?  I'm still trying to figure out why my scanner does this, or if it's just my monitor.  I need to re-scan the last one in grayscale.  After scanning some of these, I discovered that I have two scanner drivers, one of which gives me the option of doing the original scan in grayscale, and one doesn't.

Anyway, when I was a kid we all called gas ovens "butane" even though they were no longer butane, but propane.  As Hank would tell you, butane is a bastard gas.

Are any tractors these days still run on LP?  Every tractor we ever had ran on either gasoline or diesel.  An LP tractor would require extra equipment to be able to fuel it.  You couldn't just carry a can of fuel out into the field with you.  You could, but you would only get as much fuel into the tractor as it took to balance the pressure in both tanks--you would need special LP pumping equipment to pump the tank full.  I never saw any butane or propane tractors when I was growing up.  Somehow, I don't think they really caught on.

My dad had a propane system added to a Datsun B210 when I was a kid, so I'm a little bit familiar with it.

I'm just going through a bunch of the stuff I can't date exactly first.  Here's a really nice, still intact, four-page fold-out for Marlin rifles, probably from the 1960s.  It looks kind of lopsided because my scanner isn't big enough to scan the whole thing at once.  I had to do it 1/4 at time, so I just stuck them all in one *.jpg for viewing.  Click for the larger version.
