Hard to say from the pics. I go towards the peacoat of the two. You've got grey hair so the black would look great. How many of your new jackets are black and brown? I've lost track
Butte,
I'm sorta leaning towards the Peacoat as well.
To answer your question, most are Brown (the Irvin, the Oil Driller, the BK is dark seal and the GW, when it arrives is dark seal). The only black is the Aero 1930s Half Belt.
And yes I have gone grey as the wife is quick to point out, lol.
