Beauties. I'm lucky enough to have a Model 13-3 with a 3.0 inch barrel, but it's blued. It was my grail gun for many, many years. Yours in nickel, well that's sauce for the goose. Congratulations.
I have both blue & nickel in 3". Acquired in a 6 month period. They are out there but require doggedness. Also have a 4" SB, a 3" bbl, & a new 4" bbl. I had considered building my own 3" but wasn't necessary. FYI, cost of the nickel was considerably more than the blue. What you will pay is just a measure of how bad you itch.
It seems like there are a bunch of nickel 3" 13-3's out there. I lucked into one on a GB auction when I wasn't looking for one and other people were not looking at it either, great guns!
Just won an auction for that same model yesterday. A round butt. Excited for it to arrive. Was a grail gun for me too. Finally got one at a fair price. Everyone wants that model since they say it was the FBI's last revolver.
Can we post completed auction links?
