Bluing done. The ammonium chloride has given a really rich blue/black - I love it. Although the chrome moly barrel took many cycles to get an even finish. I scrapped the steaming, it was leaving streaks. Made a bluing tank from a steel fence strainer to span two burners on the kitchen hob, worked nicely.

Well, it’s taken me four years - but I think I’m done. Good thing I’m stubborn... But I’m really happy with the result. It may not be an original Type B, but it’s close enough for me.

Better anneal some of the massive load of used RWS brass so I can go hunting now…
