I would estimate the value between $1,200 to $1,500 maybe more. A 99.99% m27-2/6" with the 3 t's in blue alone with nothing was $750 about four years ago. It's twin in nickel was $750 also. Some of these in nib condition with the goodies are close to $2k.

Of course it's a new day, a new time, a new price for used S&W revolvers. If we snooze we lose.
