I've looked all over this pistol- barrel flats, extractor star, etc. If there's an N or a B, I can't find it. There are threads about the N and the serial number locations and when they were moved or omitted, but my mind only retains so much...

This pistol has crisp edges, proud and domed pins, smooth seams, crisp stampings, unturned screws, and unmolested matte areas. If it's a re-nickle, then I'm finished buying nickel pistols because I obviously don't know what I'm looking at.
