[Farmall] Tachometer

[E. John Puckett]

I've been looking for something similar, but everything I've found ran in the 
$75 to $150 range.  Does it give a reading of the number of times the prop blade 
passes, or is their a scale that changes the counts to rpm.  might have to do a 
little calculation to get rpm from a tractor engine.
