OK, now we're talkin'! That is indeed a round butt 32 HE with the sort of rare 6" barrel. Mostly we see that with the square butt Regulation Police and Regulation Police Target variants. It is a
five screw as you count the one in front of the trigger guard in addition to the four on the side plate. I've been campaigning for calling the first I-frames "six screws" to denote that they have a strain screw at the front bottom of the grip frame to engage the flat mainspring (and absent on the "Improved I-frame.")
As to value, yours is going to be harmed by the finish condition, but if otherwise in good shape should bring between $150 "friends & family" price and a top of about $250 or so to somebody buying it to shoot.
I own a couple of the RPs and a Target, but not the round butt version. I've shot the first RP I bought more than the other two, but feel like they all would stand up to a near-unlimited diet of the mild S&W Long loads that I've concocted for them. In fact, if I ever get off my duff and get a good wadcutter load (for the swaged HBWC bullets I have and the WC mould I bought, I should be able to shoot them forever. Assuming yours doesn't have problems not visible in the picture and that it carries up and locks up as it should, you should be able to shoot factory loads and factory equivalent reloads with absolute impunity.
Unfortunately, Project 616 has gotten me a little distracted (OK, a
lot distracted) and the HEs and RPs at the Lily Pad are getting a lot of neglect these days. Of course, at this rate, they'll
never wear out!!
