Vintage brown heavy winter coat

Such a gorgeous and comfy jacket, I just truly have no use for it in Florida. Please note that I had my aunt replace the buttons here which look like frosted thin mint cookies to me (haha). She added the purple flower pin to give it some flair, but is easily removed. Looks more dark brown in person  If I had to guess by feel and smell, I would assume that this is a wool jacket  Please refer to these measurements for fit as there is no sizing or care tag within. Seems to comfortably fit like a medium in my opinion  Length- approx 30” taken from the top of the collar seam Armpit to armpit- a little over 21.5” laid flat across and buttoned  Tags- warm winter cozy retro Penny lane ladies garment union snow snowy north 50s 60s 70s style beatnik union tag silky interior lined insulated chocolate brown  Over 3 pounds in box
