Thanks for the quick and concise response Mr. FlyFish! Let me pick your brain some more.
I checked in the crane area and it does have an "M" and a "2" there, so, I guess it makes it essentially a 686-2. Would the mods then have included the -1 parts?
Also if it was made in 1988 and the -1 was cut in to production in 1986, why would S&W still make no dash versions for two years? Only asking if you know, I'm not asking if you understand S&W manufacturing wierdness.
