Good evening! This listing is for an older GOODELL-PRATT N0. 448 US STANDARD ACME Thread Gauge: steel, case and test "finger gauges", tightening screws at the ends are in excellent condition, and except for the fingers on the large-tooth side, there is no rust, staining, or corrosion. All engraved or stamped text and numbers are clear and legible, the "fingers " are flat and straight.
26 test "fingers": one is the 60 degree standard test indicator, 25 are the thread test fingers... 2 1/4 TPI to 20 TPI.  The fingers on the 2 1/4 - 5 TPI side have some slight rusty stains on one surface only. The finer "fingers" are clean.
The closed unit is 3 1/2" X 1/2", and engraved:" GOODELL-PRATT COMPANY, GREENFIELD, MASS. USA, No. 448 US STANDARD" on one side.  The opposite side is blank.
This will ship in a well reinforced padded envelope USPS Ground Advantage: 7" X 6" X 1", weight is 6 oz.  eBay will handle the finances.
This is one of several auctions posting tonight, most of which are Lie-Nielsen iron bodied planes produced between  1995-2005... have a look?!
Thanks.
