AKislander: WOW!
Was that auction based in Alaska or was it online or something else?
I don't know if location would have much to do with values but it seems that here in my remote corner of the world (SW Montana) guns sell cheaper hereabouts than when I travel to distant gunshows/gunshops/estate sales.
Again, wowsers on that old timey Ruger #1-B's sales price!
I finally fingered out how to use that very informative link that "Hookeye" above relayed to me and according to his "rarity ranking" your described 6m/m #1-B scored one point BEHIND my 222 Remington #1-B and yet both score in the highest rarity level of the earliest Ruger #1's.
Thanks for that sobering input.
Hold into the wind
