I've come across a Cooper G-1 blue label jacket, size 46R, online but cannot get the seller to measure it. It's at a very low price, and I've long wanted a good G-1, but I have no idea how this would fit, nor do I know its vintage. I know that G-1s, A-2s, etc. are all over the map when it comes to fit, depending on maker, era, etc. Would anyone with this same jacket in a 46R care to share measurements (chest, shoulder, sleeve, & whatever else) and thoughts on fit (slim, roomy, tentlike, etc.)? Also, am I right in thinking that all the blue label jackets were in goat?
