44 Magnum shipped in February 1957 and later engraved and inlaid with gold by Alvin White (who also made the stocks made of stag). Mr. White did a lot of work for S&W and was the principal of Alvin White Engravers (early 60s to early mid-70s).
Mr. White's gold inlay of animals is the best done by an american engraver.
