I have one of the ex DanishUS Model of 1917 rifles. A dealer here in the UK
had a few in stock, probably 20 plus, back in the 1990s. He told me they had come from Greenland but they are ex Danish. Mine has the sighting sticker and the notch cut out in the receiver. I was told the notch is to cater for a long heavy hunting bullet to use against Polar Bears by the Sirius Patrol. Mine has an S stamped in the stock under the bolt handle. The bolt number has been re-stamped on the other side. It is a matching number bolt.
