Question I have a gun that has sn D1708. Any idea how old it may be
Answer Hello Van. N.R. Davis was founded in the 1850's and continued as such until it was sold to Crescent Firearms Company in the 1930's. Your shotgun was most likely manufactured between 1917 and 1925. I suggest you go back to AllExperts .com and go to the FIND box in the upper right corner of your screen. There enter N.R. Davis and Sons. It will take you to more information given by other experts on the subject. Thank you for asking for me. Charles Gage
