Keep the gun. Now every time you pick it up you'll have a good gun, a good price, and a good feeling about the deal/seller as well!

I was going to give you another arrow for your quiver, the box was described as excellent condition, but looks a little ragged in your photo. But a moot point now. You could sell it on eBay cheap and 'pass it forward'.

The rear side plate flat head screw under the grip is correct after WW II so the grip fits flat, pre-war Magnas had a dimple in the back of the grip so it would sit flat over the domed head screw. But then the flat head screw was used and is to this day.

The number in the yoke matches the one on the left side of grip frame (and inside of the side plate) which is correct.

I agree with James, the circled RE means it went to the service dept before sale most usually for a flawed finish and reblued.

So all in all, it's a righteous gun.
