You are looking at a Davis of Boston vintage Pea Coat in navy blue with a red lining. This coat is made from wool, has 14 black buttons with embossed anchors running down the front of the jacket. Each sleeve has 2 rows of three smaller buttons (like front) with an anchor. There is no size on this jacket but the measurements are:

Sleeves 22", pit to pit 19" or 38" around the chest and length is 32". This would make a fantastic coat for this winter weather.
