B&D-188
SOLD
There
has been no abuse of this brace in all its 150-plus years of existence,
and its few parts still run together smoothly and without significant
play. It was made by the earliest
manufacturers of Spofford-patent braces, the firm of John Fray and
Horace Pigg, in Bridgeport, Connecticut. It was made by casting iron
into a chill mold and then annealing to produce spheroidal graphite, as
there are no signs of any "fiber" or slag stringers like a
Taylor-patent brace, for example. The patent followed is that of Nelson Spofford, the earliest of his many brace inventions.
