That would have been 'the bee's knees' in the 1960s - 70s.

Those Fajen stocks with flared grip were quite popular during the bell bottom jeans days.

The high cheek piece and white line spacers are rather reminiscent of Steyr's Mannlicher Schoenauer "Custom Model" that was introduced in 1956, soon thereafter branded as MC (Monte Carlo), and MCA (Monte Carlo Amerikanische) models that were introduced a couple of years later to appeal to the U.S. market which held Weatherby's in highest esteem.

As noted by other members, WW2 surplus Mausers were cheap and plentiful in the U.S. at the time and it was popular to 'sporterize' them in the style of Weatherbys. I remember, in the 1960s and 70s, 'Big Five' and other sporting goods stores commonly having dozens of ex-military Mousies standing upright in barrels on any given day with prices we could only dream of today.
