Zarelli, was choosen to replace him at R&R and is currently active and stops in here quite often. Might want to just post your Armstrong.
I'd be happy to offer an informal opinion if you post it here. For a written opinion, send me a private message. If you post something here, please do NOT post how or where it was obtained. I prefer to start with the signature alone.
