Mark, I had one made about 15 years ago by a local gunsmith. He took a piece of steel tube the proper size and built up the edges with weld then re shaped them. Not too hard if you have or have access to a good welder.

Ned, thanks! Almost exactly what I have planned. I have a very close friend that is a master smith, I'm going to farm it out to him.

Do you still have that 1892? A photo would be real nice.
