I can't find any information on this brand as it was made in 1949.  There is no exact size to the coat on the tag so I took measurements. Based on the armpit to armpit measurement I will say this is a Men's size Large. The buttons all close it up but one of the button is a little loose as shown in the photo. This coat also does not come with any belt so you will have to get one if you want that tightened look around the waist. I think it would look stylish left open anyway. 

There are no flaws to the coat and I only listed it in good since the one button is loose and there is no belt. For a 1949 made coat I think it's condition is quite remarkable. Check out all the photos and if you want any specific area measurements please reach out to me!
