I own only one DP rifle and it is a MKI* LE. Its stamped "DP" square on the reciever. Being an LE in Australiaicon I get the feeling they demoted it to DP when the SMLE came into use to try and get some more work out of it. I haven't fired it yet, but I'll be careful if I do. I reckon your rifle should be fine, and its not like they would stamp the "DP" under the stock and make it harder to ID.
