For those interested, here's a little update.
I worked on the frame screws for quite a while. I think I'm almost there. I ended up interrupting the threads, screwing them in as tight as I dared, and then removing the heads. After that, I peened them down a bit, then worked them with the file and then a couple grits of emory cloth. Still a ways to go, but it's working. Also, removing whatever coating is on the frame, is a bear. You think you have all the faux color case hardening off, but you don't. The metal will not accept bluing, as you can see in the pictures. More sanding will be required.
I put some blue on, just to see where I'm at.
I also removed the engraved scene from the cylinder, and put a little blue on it too. Here's how it looks all together right now.
So a way to go yet, but on the right track. Still have a few details to work out, like shortening the barrel and changing the front sight to a blade and removing the billboards. But if you want a Dance in the correct caliber, this is about the only way to get one now.
