Listing on ebay a while back was for a wartime photograph identified as Lt. Rufus Crocker, 2nd Lt. 13th SCVI. I contacted the seller and asked him to send me a scan, which he did. If anyone is interested in having a copy, email me and I will send you one.

There is a R.M.Crocker listed as Co. I, 13th SCVI who entered as a private and was a First Lieutenant upon discharge.
