Thank you terc.
A gentleman who frequents that Forum has an agenda and odd, but firmly held smile opinions regarding Smith guns. DavidW, who is the LCSCA Journal Editor and Technical Advisor, usually keeps him in line.
I have seen a 1948 Hunter Arms Repair List which lists Blue, Recase, and 'Hunterize' only.
Until Dr Jim finds record in the remaining shipping ledgers documenting a nickel plated Smith, there will be no definitive answer.
