well marlin introduced the marlin model 43 in 1922 so mabey when u figure out what you really have you could try another question My Marlin Model 43 12 gauge pump (Model number is stamped underneath, in front of the trigger guard) has Pat. 1908 on the barrel. There is also a patent date of 1922. Looks like Marlin did produce the Model 43 earlier than the 1922 date you have.
50-300 USD, 12 gauge pump
Marlin made these. That brings the value up. Sold my last one to a collector (Marlin) for about 950. It was old but mint and a great shooter
