Enco has "Quality Dial Bore Gage Sets"on sale for ~$35, marked down
from ~$100. Stock numbers are TF240-0112 for 0.24" - 0.4" and
TF240-0113 for 0.4" - 0.7". Does anyone know how serviceable these
are, with or without the supplied indicator?

I bought their $30 0.2"-1.2" inside micrometer, expecting to have to
measure over the pins with a good mike, but it's actually quite good.
I aligned the marks at 0.300 and measured 0.3001 over the pins.
