As you are a Canadian resident, you must file your individual PO for a conversion cylinder with your customs department. There is a $100.00 AES Export Fee along with product and shipping charges as it is a cartridge cylinder. You may submit an order form from this link (http://www.taylorsfirearms.com/orderform) with your order and copy of your import permit so we may process the order.
We do not guarantee any compatibility with original firearms. We would recommend a Pietta cylinder, as they are longer and you would have more material to work with to fit to an original firearm. They are $240.00. You can locate them on our website for more information.
Thank You,
