 Drew, how do you fancy this example? It may be yours? I have it as a Ferlach sourced but I don't remember. Kind Regards, Raimey rse

It's an acid etched probably 4 Iron Hufnagel.

Thanks Drew. What's that disturbance in the force there?
Kind Regards,

Can't say Raimey. It's not uncommon at the breech, where the ribband is thickest, to lose some pattern symmetry.

Raimey,
Not sure which “disturbance” you are asking about, as I see at least two.
The circular defect near the midddle of the photo appears to be from forge scale on the anvil being pounded into the damascus, causing a displacement of the edges of some of the layers.
There is an H shaped defect very near the breech end. This is easier to explain. This is caused by decarburization of the steel element in the damascus, due to it being exposed to the forge fire for an extended amount of time. Whenever steel is in the forge fire, carbon is being burnt out of it. The decarbed steel becomes simple iron and etches white. The H shape was caused by welds that were not quickly closed and were open in the fire for several more heats than adjacent areas.

What a blessing to have a contributor who has actually done, rather than just read! "The decarbed steel becomes simple iron and etches white." I thought iron stained black?? More examples that are now explained

That was my pure guess about that oblong bullseye defect(?). Maybe a scarf joint, one strand curving a bit out of the barrel then when it was ground even it showed a little like and end not edge pattern. Thanks Doc Drew and Steve for the interesting contributions.

Steve:
Yes, you correctly identified the culprit in the middle of the image. I surmised it to be heat related but never considered foreign material. Is there a time span during the day you prefer to roll your own?
Kind Regards,

I have been a member on this board for several years now and I have to say that I think this thread is the most interesting, informative group of posts I have seen in all those years!! It was this board and a couple of e-mails and telephone conversations with Dr. Gaddy that turned my thinking around about Damascus. I did own two Damascus pieces, a Remington and a LeFevre, but I let the LeFevre go in exchange for something else that had caught my eye. I shoot the Remington regularly. Thanks to all and to Dave for this wonderful source of information.
