If you are interested in the 18th SC you may like to see this. I have never posted a picture using this method so you may have to copy and paste the link into your browser. If you look in the upper corner you can faintly see "18 SC" stamped in the wood. This is an Enfield stock that was likely broken in the Crater explosion and found in a bombproof at the Crater in 1869 by a Miss Sadie Willey of Richmond, Va.
