Burberry London Camden car coat

I believe this is the Camden style car coat from Burberry. The size tag is missing, but my husband wears a sz 42 and it is too big for him. I have the measurements for you. He thinks it might be a sz 46? It measures 21” from shoulder to shoulder lying flat, 25” from armpit to armpit, 23.5” sleeve length, and 39” in length. It is in excellent condition, looks barely worn except for the missing sz tag. Lining is in excellent condition and all monogrammed buttons are intact as well as spares which were in the inside button pocket. This is on the website for $2,150.
