Raynor,
Looking good, man.
Just a note on metal finishes for NW guns. English and Belgian made trade guns generally had "bright blue" barrels suggesting a charcoal blue instead of a rust blue. I just read Parson's 1952 article "Gunmakers of the American Fur Co" and he also quotes an order from AFC to the American builder John Joeseph Henry for 580 NW guns in 1828 specifying maple or walnut stocked with square butts, ordered by barrel length, with 6" locks and "the barrels to be of bright Blue, and the Stocks to be well varnished." It appears blueing predominated on these guns long after the rise in popularity of browning in the US.
