I just got a 12 ga Remington Model 11 (made in 1921). It's in great shape - even the fiber buffer in the rear of the receiver is intact. But, somewhere during its past life, the bolt slammed forward without the barrel in place, and the forward edge of the ejection port got a little peened from the operating handle. It doesn't interfere with anything, and there's no cracks in the metal. So, should I leave it alone or try to smooth it out somehow?
