I would post this also on the "small arms" board on this site.
That's likely a decent price - but without seeing it clearly, who can know the value?
To some people, "fair to good" means "considering how old it is and how hard these were used, it's pretty good" and to others, condition doesn't take into account how old it is, or how hard it was used - the price takes that into account, but I think a gun's condition is not adjusted to reflect age or use.
That means that there are some models where the usual range is poor to fair,and there are no fine or excellent conditioned examples known to exist!
