as for your marlin lever action, (Including Models 1881, 1888, 1889, 1891, 1892, 1893, 1894, 1895 and 1897.) Note that records are chaotic as all models were numbered in a single serial number range, and numbers are often duplicated, and the dates recorded are apparently shipping dates, not dates of manufacture.
shipping date of 1897. not sure of the model, google all the above and see which one matchs yours. it could possibly be a first run model 97.
