Hi Jim,
Here's what I've got for mine. I had one and 1/2 original rods to copy. The curtains are reproductions the former owner bought while attending Beltring some years ago.
The rods are 5/8" wide, 3/16" thick, and 18" long. I had to cut mine down a bit to work with these curtains. There were also two tapped holes in the rods for screws to attach to the curtain (I assume). The bottom is tapered from round to a square to fit the slots in the doors. I also angled the front rods to match the angle of the front of the curtains.

PS.. if anyone has pics of what the top part of the rifle holders looks like, I'd sure appreciate it!
