Dana,
Nice looking lady smith. I took mine to the Tulsa gun show a month ago and did a little show and tell with the bigger S&W collector/dealers. Also showed it at the S&W forum booth. The biggest dealer there said he had seen very few 6" target models. Interesting yours has smooth grips and mine has checkered. Did you check for a SN on the right hand grip? Should be in pencil. Mine was hard to read with my old eyes. Took pictures of mine, then played with the brightness and contrast with microsoft picture editor. The serial number was fairly clear in the enhanced pictures.
Be careful if you remove the rear sight to check for a serial number, I ended up using a jewelers screwdriver as the screws are small.
My Ladysmith SN 236XX was shipped Feb 1914. yours 222XX probably before that. Definitely worth a letter after the first of the year.
