In re the OP.............Eastman, very authentic particularly these past few years as they have revamped and intro'd new patterns.
Since you are on the GW waiting list, have you considered a much cheaper A-2 just to get you by? Perhaps a used something on eBay....Cooper, Willis and Geiger, etc. These are not high end brands but if you are waiting on a GW, paying about the same for another jacket might not be needed. Its your call of course. I would have to say that these days I get as much enjoyment wearing a beater, cheaper jacket than my high-end ones.
