Marlin No. 24 12 Gauge, Questions
 

OK guys, I have the general background. Marlin No. (Model) 24 12 gauge shotgun. I believe it was made between 1909-1910. The barrel is about 19 inches, so I assume somebody shaved her down a little? I know that some think they're a dangerous gun, but I cleaned this one and found nothing wrong with her, so I put her through her paces on the range and she was as good as our modern issued ones.
I'm looking for.....
History.
Grade.
Anything interesting.
