Default what is this mystery pratt and whitney tool?

I originally posted this in the metal working newsgroup, some folks there
thought the part might be recobnized by somone here - so, it's worth a
try - any clues?

thanks:



I think this is probably quite old, but so far I have no idea what it is
(or
was part of) - there is another like it that has been sharpened to use as
a
boring bar - clearly that was not its original purpose. the one pictured
in
the drop box appears to be original - but orignal what, is the question.

here are the links to the drop box:

Anyone got any clues about this item?

The text file from the drop box is reproduced below:

Mystery Pratt & Whitney tool - the cylindrical shank is exactly .500
inches,
it says on the

shank, the following:

NO. 32
HS.-36
E-12

P&W
MFD CT
Made in USA

it is NOT a drill bit. The part that extends beyond the 1/2 inch diameter
shows a wear line

like it was riding in a keyway. The point seems to be lathe turned, the
1/2
inch shank

appears to be ground

My first guess would be some sort of gagueing equipment. I have run across
quite a few truly odd P&W gages and accessories for gage sets. They were
willing to make some very specialized gages for a lot of unique
applications.
