Great job on the color matching! It looks spot on to me. As a reference point, how many cycles did you have to rust/card this to get to that level?

I'd be interested to know as well. Any resource you used, or could recommend, on how to get a good rust blue finish?
Unfortunately no drawings. I am still hopeful someone will have a extractor or repro-extractor for sale that I find.
Since the band had already been bead blasted, it was fairly porous -- which is exactly what you need for rust bluing. It tooks me 5 cycles to get it where it is. I basically ran a couple cycles then compared it to the barrel until I got the color I wanted. If my barrel had more bluing on it, it probably would have taken twice as many more.
I used this stuff to inhibit the rust: http://www.laurelmountainforge.com/barrel_brown_inst.htm
For those unfamilar, the process runs like this (with deblued metal - white vinegar removes bluing)
1. Degrease
2. Apply rust inhibiter
3. Hang out to rust in a moist environment ( I hang my parts over (and partially in) a pot filled with water. Some folks have enclosures that they keep humid.
4. After a good bit of rust is in place, boil rusted parts in distilled water for 5 min - rust turns black
5. Card (ie scrub off with a fine steel brush) the black "rust" to see the blued metal
6. Repeat steps 2-5 until bluing is dark enough
Well the process is well documented in this thread if you go through all the posts. In short though:
- Dissembled completely
- Scrubbed all metal parts with Big Frontier 45 pad or brass brush
- Soaked metal parts in Kroil
- Scrubbed all metal parts again after taking out of Kroil bath
- Cleaned off all Kroil, reoiled all parts with gun oil
- Cleaned wood hardware with very dilluted organic dish soap and let dry
- Reassembled.
