Siace (pronounced si-AH-cheh) is a fine Brescian firm which produces a wide range of shotguns and double rifles. In addition to their own line, they build the Superlight SXS for Dakota Arms. They make a hammer gun that always sets me to drooling. I haven't seen any in Canada. Which model are you looking at?
Do not even think about a chrome lined bore. Siace knows how to make highly polished barrel bores, coating them with chrome would not improve them. Just remember to clean the barrels once in a while, although with this gun I suspect you will be polishing it all the time anyway. Nice find - pics?
