I found a stainless lower/heavy barrel upper Mark II. It is a nice pistol. This had to be made up by someone, correct? Not factory, right? I have a serious hankerin for it! What is a FAIR price, despite it being a put together gun. Condition is 98%.

I remember that my local Cabela's had a bunch of two-toned Rugers in their "Gun Library", some years ago. IIRC there were MK II models, and I
THINK I remember some two-tone Single-Sixes and/or Bearcats, at the same time.
They had several different configurations, and were all reasonably priced. I remember reading some threads about these on the various forums, back then. (
Edit: it looks like I might be "remembering" more varieties than I actually saw. The 5-1/2" bull barrel seems to be the two-tone model made for Outdoor Sports.)
IIRC, they were new guns, but limited production "Distributor Exclusives" that Cabela's chose to display in the Gun Library, vs. the regular display cases.
I thought they were neat, though "not really my thing." In retrospect, that would have been the time to grab the whole works.
"Instant Ruger display" material! (I like the displays collectors put together, but they're "not really my thing," either.
