[are all #1's chambered in 458 WIN MAG the Tropical model?] - Yep.
[What would the value be on a Ruger #1 458 WIN MAG in excellent condition be? ]
In my experience, the "askin's" always high, but the "selling" (when they finally sell) ends up being a LOT lower - as not all that many buyers actually end up in hunting country, where a .458 would be of good use.
Curiously, most I have seen F/S used were "only shot once (or twice)", and came with a box of ammo containing 18 or 19 rounds.
