I’m unsure of the origin of Pincher but I can add to ssomething Pinchers wore and they were YARKS or YERKS. They were pieces of string or twine tied below the knee to keep their
trousers out of the muck,in earlier times Sugans. were used.
PELTER or Walking PELTER was a Ganger who walked up and down roadways under
construction.Later some used bicycles but the advent of the Jeep made the job
obsolete .
