This photo appeared recently on Ebay and shows a union artillery private with a Kerr revolver stuck in his belt. While I believe the revolver was probably a studio prop as heavy artillery men didn't carry pistols unless they were private purchase and there is no holster on the man's belt, it is a very rare photo showing one of these English revolvers. Based on the background which appears to be a professional photographer's studio, this photo may have been taken in a large city like Washington and the artillery soldier may have served in its defense. Does anyone have another Civil War photograph showing a Kerr revolver? I've posted it here instead of on the photograph forum specifically because of the interest in firearms.
