THE STAMP ISN'T VERY CLEAR. I WAS HOPING TO FIND OUT WHAT MODEL IT IS. PAT'D NUMBERS ARE MAY12,1896 JUNE2,196 MARCH29,1904 AUG.7,1906 MARCH24,1908 MAY19,1908 NOV.23,1909, AND DEC.211909. THANKS FOR YOUR HELP.

Answer
There were a number of different model with those patient dates.
My best guess is its a model 24 or 26
I would ask the question at the Marlin Collectors Association with a photo.
