Coneten: i've never heard the number being THAT low, but it's not a lot, that's for sure. I've heard as low as 839, and as high as 4000. That's still just as rare as Irwin-Pedersen original production guns!

Any chance that you can ask them where they got them from?

And also: If you can spare a minute, can you take a look at a few of the rear sights? Most have the "windage-adjustable flip" - style rear sight, and I wonder if these are also set that way, or if they have the distance-and-windage adjustable "ramp-sight".
