I have been trying to snag one for a long time, with no bluing I would have a hard time going over $300 unless it was really clean otherwise. I was at a firearms auction a couple of weeks ago and there was one with little bluing and some light pitting. I bid it up to $275, I think, but didn't meet the reserve.

...I would like to have one of those, but $300 would be about my limit in that condition.
