Goshes it's big. pickett's most complex rule. pretty much every scale you could ever need and then some. maybe not quite as nice as the dietzgen equivalent, but it's wider and yellower.
This is the only rule i've ever bought on ebay. Most of the stuff there is way overpriced, but this wasn't so bad. i think i just got lucky. the rule was missing the adjusting screw in the lower left corner when i bought it, so i took one from the N1010-ES. Pretend this fascinates you.
