It doesn't hold the second shell back so it jams two shells on the flipper. It has a simple problem loading shells from the magazine. It's in great shape, no marring on the stock, the receiver and barrel are clean, no marks or scratches but a little shy on the bluing, but it works pretty good, nice and smooth. But it had been passed down through his family in western Illinois through several generations. It was given to me by my nephew who was not into guns. From what I have read it was likely made sometime before 1910. Just read your thread on the Remington Model 10 and decided to join the forum. Hope you're able to get yours sorted out. Remington sold a few Model 10A shotguns to the military for WWI (about 3500 IIRC) that are now the wet-dream for collectors ranked at the pinnacle only with the WWII Ithaca Model 37 trenchies. Also the Remington Model 10 (a Pedersen design) looks very similar on the outside to the Remington Model 17 (a Browning design - and the forerunner to the Ithaca Model 37) - on the inside the Model 10 and Model 17 are completely different guns. Kinda cool the Remington Model 10 formerly known as the Remington Repeating Shotgun seems to appear in drawings on Remington literature as early as 1906 and patents as early as 1903. If you can find your own stock that would be great. now finding a smith that knows what they're doing with old gun like this is going to be the real challenge. Thinking older guns like that were usually hand fitted so one might think a 'new' bolt would need to be fitted. Remington started doing their 'barrel date codes in 1921, so it sounds like it was built before that. Call Remington at: 80 to get a year of manufacture all you have to do is give them the SN and they can usually give you the year of manufacture.
