Interesting rifle Eric! I believe that I read/saw somewhere that native Greenlanders had 45/70 version of the Dane Krag for Polar bear hunting, but I can't seem to place it now!!I wish I knew something more about it to help you out. I have a 45/70 on a Dane receiver (previously bubbaed) that I had made for me and a single shot version on a US receiver. When you establish a price I would be interested in first refusal. I hope we hear more soon
