I think you meant to write the photo clearly shows it is not a "Colt Copy" made by Leech and Rigdon?Bannerman had a lot of Remingtons and he found he could sell a "CSA" marked gun for a lot more so guess what? The engraved backstrap attributing the revolver to Gilmore is on a pistol "made by the Southern firm of Leech & Rigdon. The revolver was a copy of the Model 1858 Colt Navy Revolver." The photo clearly shows that it's not a Remington.
Thanks for clearing that up for me. LOL about the Longstreet Revolvers!!!"made by the Southern firm of Leech & Rigdon. The revolver was a copy of the Model 1858 Colt Navy Revolver." All in quotes was copied directly from the site. It's a little confusing and I had hoped to show that the photos and text were somewhat ambiguous. The text was under the photo of what is obviously a Colt style revolver but a first look it would seem the author was describing what he thought was the backstrap of the Remington and then calling it a L&R. After looking at the article a second or third time I believe he had moved on from the Remington to the single photo and description of the L&R. The way the photos were ordered on the site at first it seemed the last photo, the L&R, was included in the series of Remington photos.
As an aside I have a brace of brass framed revolvers which were the personal property of General Backstreet. Their value is somewhat diminished by the fact that very few have ever heard of him. He kept a very low profile throughout the War.
