Based on some new photoshop experiments, I’m starting to think I was off on my Civil War Carriage Olive Green assessment. Check out my updated page.

Also note that I discovered a new City Point Photo on the National Archives pages.
This is listed as at unknown location, but it clearly is taken on the ordnance wharf at City Point. You can even see lettering on the carriage that indicates that it came from Washington Arsenel to City Point. The Library of Congress call number is: LC-B811-2582
A while back I found a photo at the National Archives that was identified as taken at City Point, but was actually taken at Belle Plain. I send an email to the administrators and they said they didn’t have time to verify my assertion and make a change. This item can be found on the National Archives website by searching for ARC identifier 529319.
