Is that cyanide or char and bone? Do they have a web site?


Cyanide. Can't do Bone and Char on a Miroku Low Wall. Something about the lever and a ball and spring within. No website that I am aware of, but that could have changed as I had this done several years ago. I just had it polished up to about 600 grit and sent it in. Turn around in about 3 weeks. Turned out well IMO.

PS. I got their info direct from Browning.

Double PS. This is from the single shot forum a few years ago:

The following is a paragraph from my book on the Browning BPCR's. "The color-casehardening process was developed by and licensed from Tom Ivanoff, Tom’s Gun Repair, Inc. , Cody, Wyoming. It’s a potassium-cyanide-based process developed for volume firearm production. The process does not affect the heat treatment of the steel and the resulting case colors are reported to be more durable than those created by the traditional carbon-based “bone and charcoal” processes. The case colors on some rifles are muted and leaves a lot to be desired, while others are quite brilliant and attractive. Miroku reportedly had some problems in assimilating the process into their production flow. As a result, the differences may have been due to their inability to control the process from lot-to-lot. Also, over time the case colors can “wash out” to some extent due to natural UV radiation and the use of penetrating oils on the finish. More details on case hardening, case colors, and protecting the case colors can be found in the Appendix chapter titled “Case Hardening & Case Colors”.

By the way, Signal Mountain Gun Works owner John Witt bought Tom’s Gun Works in 2003, including the rights to the process, to which he has made significantly improvements. I understand that all the Browning & Win. color casehardening is now done by Signal Mountain.

Not as pretty but looks classy when done right, is a French Grey. Just an alternative I thought worth a mention.

It’s an acquired taste. Better than a coin finish, not as nice as good charcoal case colors. But few things are worse than poorly done charcoal case colors.

No, Ed, it wasn't you. It was your "master gunsmith Ed Landers", wasn't it? The one to whom you sent your guns to be torched, and then defended the process. What's the real difference between doing it yourself or commissioning it to be done? At the least you were/are a willing accomplice.

You drug me back into this with the above post. Go ahead, try to lie out of it again.

Do you remember making this statement defending "master gunsmith Ed Landers" pitiful torching process?

Case colors have been safely restored to near original bright appearance.

If that is not defending his torching I don't know what is.

What boggles my mind, and what I learned here, is that Cyanide hardening actually is a harder surface than bone and charcoal hardening.


Socialism is almost the worst.

Harder, and it seems to last longer as well. Personally, I do not believe that UV light does anything at all to colors - they don't fade, they do wear. And acidic anything (sweat?) will eventually remove them.

Brent is right! Oscar did extensive tests and found light has NO effect on case colors. It is wear no light that removes color.
