Please help me find info on family relic

[distra]

I have just inherited a 90+ year old pump shotgun. It was my grandmother's father's shotgun. She gave it to me to keep it in the family. My great grandfather would hunt racoons, turkey, goose, etc with it. My grandmother is 91 and she has pictures of her standing next her father while he cleaned it. Almost brings a tear to your eye thinking about it. Anyway, the only markings on it are the serial number and a word "National" on the butt plate. I have attached a few pix to help out. It has a hammer and the bolt moves fully back to cock the hammer and chamber a round. Any info would be greatly appreciated.

oh yea! it also look's like a marlin model 17 but the model 17 did't have that band on the mag tube . you know the band just in front of the reciever.

Barrel length is 29" and it looks like a 12 gauge (barrel diameter is just shy of 0.75"). I plan on having it a while and hopefully passing it down to my son. 1910-1915 fits grandma discription that her dad picked it up a year or so before she was born. She can even remember him cleaning it, but told me the cleaning kit has long since been lost.

I believe Full Metal is right, Looks like a Marlin Model 30. National would be a Trade Name or Store brand ( Think J. C. Higgins and Sears ) used on shotguns retailed by good old H&D Folsom and Marlin did make trade name guns for Folsom.
