I have a 3rd model Ladysmith 6" barrel target model. Took it to the Tulsa gun show to get an appraisal. Got a lot of OOhs and Aahs, but finally got to a S&W broker collector who gave me an appraisal of 6000 to 6500. he offered to buy it at someshat less than that but I plan to keep it for a while.
As with most collectibles, condition and original finish is everything. I lettered mine, it has a Feb 1914 ship date.
Here's a couple of pics.
