Vintage Carhartt coat with hardwear condition issues

Carhartt coat size large. Fabric itself is an overall great condition. This coat has a heavy canvas outer shell with a thin mesh liner. I have done my best to photograph all issues. It is missing the snap cover on the middle snap but the snap itself does function. The zipper does not function. It is missing teeth toward the bottom. It will need replacing, or could be repaired to be shortened. Coat can be fully closed with the snaps. This coat does have an option for a hood, but there is no hood included.
