Pedersoli Rolling Block .50 Caliber made in Italy

I am selling my late father's gun collection. I am NOT an expert and am trying to do my best in accurately list these guns with the info I can find on the gun as well as on the internet. Please ask me questions and I am open to additional info and advise. I am pretty sure this is a Rolling Block type of black powder Rifle. This rifle doesn't have too many marks. It is in excellent condition, clean and with no scratches. It has beautiful engravings and the wood stock is beautiful ribbon grain. Barrel is 28" long. I found a photo of a Model S882 that looks to be the same as this one. Included in my $50 shipping charge is a new black hard plastic foam padded gun case.
