I've had Classics in 270, 6.5 x 55, 35 Whelen, 220 Swift, a 243 with a Dec. '77 date code so a very early Classic and one that hasn't been mentioned, the 7mm Weatherby. Only one I have ever seen.
Two stocks Remington got right were the Mountain Rifle and the Classic. I have McMillans in both patterns.
Jim Carmichel designed or had a great deal of input on one of those stocks. I don't recall which one, but I think it was the Classic.
