I just found two listed for sale on on-line auctions. asking starting bid is $300+-. Sellers state they are in very good condition. apparently made between 1914-1927. I am looking for a stock for one. hope this helps.
are sure it's not 1899 instead of 1809? I just held one of these rifles today and would like some information myself. the one I held had the patent date of August 29, 1899
