I have an Ace Mitchell Tru-Pitch Gauge Kit that I am looking to sell.  The kit has been used but comes with all 21 of the hole inserts and pitch ruler.  The hole inserts range from 19/32 to 1 1/8.  This is a great set if you want to check your pitches but don't want to spend a ton of money on the higher end pitch gauges.  This is what I used when I first got into learning about ball pitches and layouts and wanted to check my drilled balls.

Here is a link to a picture of the kit.  I do not have the cardboard with the labeled slots.

Make me an offer if you are interested.
