dating coats

Just ordered this McGregor Raincoat online, I wasnt able to request a clearer image of the label so I looked up a similar one online. Since the package has not yet arrived, I havent checked it for union labels. Can anyone help me date this coat and maybe guess the material? Thank you everyone!

I looked around and couldn't find anything that answered my questions. I recently acquired an antique Robert Hall overcoat, based on time the company was in business it had to be made between the years 1937 to 1977. I'm considering selling this coat and the more information I can get the better...
