Not to be provocative here but I have learned this lesson the hard way. The term "special order" needs to verified to be used with Winchesters. One needs to be very wary of this description because when it is legitimate you will always pay a premium for it. If it is indeed special order odds are it will letter. Anything "special order" on a Winchester is worth lettering. The other is length of pull. The length of pull was very consistent gun to gun. If one is a 1/4" short it has been cut. Again not trying to rain on anyones parade just passing along from experience. Personally, short of the pre-war customs I love, the low comb pre-64 & Lyman Alaskan in G&H mount or Redfield Jr. is the "Riflemans Rifle". Fall is coming, hope all is well with everyone.
