My apologies, I had typed out a more extensive reply but had timed out on my login so lost everything when I hit submit, which led me to my abbreviated reply.
I have no pouch and a set of 6 (7/32 to 3/8, so I am probably missing the 3/16). On one of the large flats of the handle is stamped: XceLite
PATENT APPLIED FOR
on the other handle flat is: PARK METALWARE CO. INC.
7 - 7/32
ORCHARD PARK, N.Y.
The numbers in the middle change by sixteenths: 8 - 5/16 and so on.
About 70 years ago my father got these second hand with a lot of other tools that were 90% "MAC" brand.
My daughters will be here in July so I will get all knowed up on taking and posting pictures and become a better contributor.
