Many thanks. Good to know it was possibly involved during the civil war with my home state troops. At least 2 of my ancestors served from western Pennsylvania, both ground pounders though. Please excuse the length it took to reply. We were traveling out of the country. (Hopefully remaining in good health at this time.) All reenactments in Florida, where I live have been postponed so it may be a while before I carry it with Second Florida Cavalry. I have fired the plastic blanks successfully. I have both the original and a center fire repro block for it.
Again thanks and I'll continue to lurk unless I have more to contribute.
