Jim,

While I am still learning (in a frenzy) I can shed some light on this.

I found, much to my chagrin, that one of my "collectable" Lugers had been reblued. The way I detected it follows:

With a 10X loupe I carefully examined an area on the barrel which looked a little rough. Under the loupe it was clear that the "rough" spots were actually tiny rust pits. The problem was that these rust pits had the same beautiful blue finish as the barrel, all the way to the bottom of the pit. While I admit to being an amateur, I am pretty comfortable that rust does not pit a barrel in that manner.
