That is not a rare gun. It's an early 250 F. My Uncle has one. I've seen other 250's in same configuration. The ones with the integral front sights between about 1920/21 and 27/28 are definitely nicer and more desirable than the later ones IMO. An early G in 250 would get my heart racing a lot faster

This rear dovetail sight is wrong. The gun looks original but it's not in high condition.

If I wanted it, which I don't, I would not give more than $1000 as is.

Even that a stretch.
