not so fast! just trying to find some basics in serial number's and I need more informations( need all)

what do I know? your dreyse patent rifle 31039 have no proof so before 1891.
I have an unusual but obviously very late double gun 33290 with Franz v. Dreyse so till 1894. and a M 88 sporting rifle 37531 with Munition's & Waffenfabrik Sömmerda made between 1899 and 1901. your rifle must be very close to 1891 dont you think so?
