Well Ed this could get interesting...

But to answer your question, I think its Cyanide.

Here you go ed. I guess you have forgotten these threads from 2009, but have successfully baited a response to your every 3 month sincere seeking of case color knowledge

The images are gone from those threads, so here's the real thing for Forum members genuinely interested.

Note the "ghosting" around the pins.

Cyanide colors are nothing new.
Some turn-of-the-century hardware store singles had bone charcoal colors - an Iver Johnson. Note the 'ghosting' again

Harrington & Richardson cyanide colors

At one point Krieghoff actions were reportedly Bohler chrome-molybdenum-vanadium but now are (likely - they ain't saying nor is Beretta's "Tri-alloy") AISI 4340 Cr/Mo/Ni
It is hard to obtain bone charcoal case colors with 4140 or 4340.
AISI 8620 (also Cr/Mo/Ni) is more easily case hardened (carburized), or nitrided

Reportedly Krieghoff was using some form of chemical coloring for the actions that are not silver nitride

K-80 Super Scroll possibly chemically colored - no 'ghosting'

This is likely bone charcoal with the 'ghosting'

wow, what a plethera of data images of a variery of shotgun case colors...

valuable indeed for future reference...in fact, so valuable to change the name of this thread to:

"shotgun case reference guide"


and it would be valuable if others would ad images of shotgun case colors not referenced above...

original or redo, so long as ided as such...

I always like the colors that come from Richard St. Ledger in Birmingham. I believe he is used by Purdey and Westley Richards today, although not 100% certain on that.
