Bill Ghio asked about this co. making rules and Don Screen provided some
info about their doing so. Don said his source said Upson was part of
the Standard Rule Co.; my source (the DAT) has it the other way around.
Andrew Upson was Pres. of Standard Rule before folding it into his Upson
Nut Co. in 1888. Some or all of the Upson Nut Co. moved to Cleveland,
OH; that may have been around 1893 when Stanley took over part of their
business and possibly their CT facility. A 1911 source shows the OH co.
making hardware and such, but no tools.

Several other rule makers, including Upson, used Stanley's numbers on
their similar rules. The #68, by anybody, is common enough to have no
special value.

Best Wishes,
Bob
