I am not a military uniform expert (hence the post) but I can tell, some things from B&W photos. This is almost certainly a gray uniform.. The buttons can not be a dark color (black) they are either gold or silver.. The shoulder boards are either Navy Blue or Black. The buttons & the boards are really what have me stumped. I appreciate all the responses. I can go into my original colorized photo & make any correction if we can determine exactly what they should be. Also the uniform shirt under the jacket what color would it have been? Khaki?
