Here's a nice Sargent Brosnihan-patent nut/pipe wrench that
arrived in the donations this week. Unlike the example on the
Alloy Artifacts site, the 'Brosnihan' and 'Sargent' stamps are a
single integrated stamp
"SARGENT BROSNIHAN
PATENT
SEPT 4 1900"
One ear of the sliding jaw is broken off, but the rest is VG,
maybe VG+ I think.
(That's a Winchester 6" screwdriver that arrived with it,
keeping it company. In a box of rusty stuff, these two spoke
to me.)
