Thanks for everyones time in answering this post! If anyone comes up with a source for the Pieper photo, I would certainly appreciate knowing where it came from. Ill do some more internet searching to see if I can find it.
The gun barrel images in my document are all sourced from the internet. So, they are public domain. Though, I would very much like to give credit to those from who they originated and also extend the courtesy of asking for permission to use. My intention with this current document, is to post it on this forum, as well as a couple other internet sites. So, I have no plans to put it into print at this time.
I would eventually like to include the information in this document, into a much larger printed book on damascus gun barrels; if I can find time to write it. Permission to use images in the printed book will certainly be required. I would wish to have high quality images to include in a printed book. But, I have found it difficult to find really good quality photos of damascus gun barrels. I wonder if it would be possible to locate some of the guns with unique damascus patterns and have them professionally photographed. Another day.
The photos of the A. Arthur gun came from Rock Island Auction. Perhaps the Pieper gun also went through their auction house and the photo originated with them. But, the Pieper image is not of good quality. Rock Island seems to have professional photographers taking photos for their use. I would have expected a better quality image of the Pieper barrel, had it been one of Rock Islands photos.
