Gentleman
... Just want to thank all of you for posting this discussion and exchange of information. It has been most interesting.

Having done a fair amount of gravestone repairs and conservation in past years on confederate graves and visited untold number of cemeteries over the decades doing research and general interest. I had noted differences in the existing stones, but hadnt had reasons to think far enough to determine dates of possible manufacture. Having ployed and done repairs in Richmonds Hollywood Cemetery for many years, the data posted here helps it all make sence now..lol.. Also treked up to Elmira to seek out several ancestors buried there. Very interesting stuff... thanks..
