Herb - In my experience in the Trans-Mississippi, I don't think that there is much use for the term "standard" in regards to the outfitting of Reb Cav.

The ammunition issues and arms reported in units were very much a hodgepodge. Having said that - I do think that the Cavalry was issued some of the best arms that were available for mounted service. Yes, I know that there were regulations indicating what - when - and where arms and equipment would be issued and required. But, they simply didn't have the material to stick rigidly to the Regulations and simply did the best they could. But I have not seen much to indicate in my neck of the woods that there was anything like a standard.

The arms and equipment for one unit in particular comes to mind in my research. In LATE 1862 - they had - .69 muskets - Sharps - double barreled and single barreled shotguns - Enfields. Private saddles and captured saddles. Private and captured bits - all carried by horses that were by then, mostly CS Army issued. And yet, this Cavalry unit did not list a single pistol or sabre in their arms.

Now perhaps some other units had a lot more standard issued clothing and equipment - but, it seems to have been a rare thing West of the river.

Hope that this is of some use - Take care
