A 12ga Model 100, 26" barrels, should run somewhere in the 6 3/4# range. Nice weight for an inexpensive production gun.

Re the faux finish, as I recall, the only ones that had that were the 280's, although I might be misremembering. But I'm not sure I've ever seen a 100 with anything but very plain-looking wood. OK stuff but plain. I don't think the grain-painters did any work on those.
