Jerry Glaser sold a gouge called the Stocksdale Gouge under his old company name "Turnmaster Tools" back in the late '80's and early '90's. Superbly made, the handles were made from goncalo alves, with a stainless steel ferrule. The high speed steel was M4, twice as wear resistant as M2, and used today in Oneway's line of gouges. If the gouge you bought fits this description, consider yourself very fortunate!
FYI, Jerry made the very first HSS gouge for Stocksdale around 1960, when everything else made was from high carbon steel. He formed Turnmaster Tools to sell HSS turning tools because the main manufacturers at the time were not interested in changing from their method of toolmaking. In my opinion, Glaser singlehandedly changed the woodturning world with his introduction of HSS tools.
