I contacted the importer of Paolo’s pipes, David Field, and found out the mysterious “C” means the pipe was complimentary. I did not ask David for whom it might have been a gift. Maybe it was for David. It was not complimentary to me and thus it will not be complimentary to you, although I suspect my price will be quite appealing. It certainly is a handsome pipe, in excellent condition and a Grp. 4 size. The striations in the ferrule lead me to believe it is bone or perhaps antler. The brindle stem is quite flat and thin and so, to me, very comfortable. The blast is deep and sharp and shows lots of cross grain.
