Thanks for getting back to me UCVRelics. You helped me with my Sharps M1863 carbine recently which was very much appreciated. My problem is this; a number of years ago I purchased a Colt Model 1861 revolver serial number 2852 at the Cleveland gun show when I was in the US on business. It was identified to John M Martin, Co F 13th Illinois Volunteer Cavalry with accompanied paperwork from SRS stating this. I met Dave Taylor at the show and he confirmed it was all good and reliable. This has all got to be 25 or so years ago. I sold the pistol with all paperwork some years later and always regretted it. However, recently, I saw it in and auction here in the UK but there was no paperwork with it. I purchased the revolver and wanted to contact SRS to get replacement paperwork and the rest, as they say, is history. I'm assuming the information came from the Illinois cavalry company books but I have no way of accessing these here in the UK. I posted some photos of the revolver on a previous thread. Not sure where to go from here. Obviously any help is appreciated.
