MPG calculator

[Mike Szadaj]

I came across this MPG calculator. There is one feature that makes it pretty unique. In the lower left-hand corner, you insert your car key into each of the three rotating number wheels. You set the numbers, ignoring tenths of a mile, so that you can easily remember how many miles you have driven. It has a clip on the back so that you can attach it to your sunvisor.

I prefer to look at it like a gearhead’s slide rule

That's pretty slick for back in the day. No cell phones with calculators back then.
