Winchesterpoor: I personally would not even consider buying either of those Rifles - except at "parts only" prices!
The barrel on the 257 has been removed, reblued and replaced with a POOR job of proof stamping.
Dittoes on the stamping of the Super Grade 30/06.
These "computer sales" brings to my mind the several times I have been approached to "bid up" questionable sales via internet sites.
I have bought many items (including some guns) via the internet but would NEVER even consider purchasing a collector type Winchester through that venue - just to much money at risk via a remote seller!
I have and I have bought MORE than my share of collector Winchesters the need to risk my hard earned monies with this type high risk sale is just not there.
In my opinion both of these Rifles deserve a pass for many reasons.
Hold into the wind
