My bad, the spelling is Robert Kain. Deceased.
A google search will bring up some info on him.
He also engraved the Marlin “Brace of 1000”
Commemorative Model 39 and 336 Rifles.

Robert Kain, of McIndoe Falls, passed away at home Wednesday evening, Nov. 19, 2008, surrounded by family and his ever-faithful dog Sammy. He was a quiet and unassuming man with great strength of character. He will be greatly missed by all who knew him.

Bob was born in Staten Island, N.Y., Aug. 1, 1928, the son of Edwin J. and Katharine (Johnson) Kain. A freelance master ornamental firearms engraver, Bob did beautiful handcrafted custom work for the nation's gun makers. He was also the author of two books.
