This is a gorgeous looking and sounding guitar with big rich tone. It's really near mint. I only downgraded it to Excellent because when I was taking pictures I noticed a few very light fine lines in the finish. They are not finish checking. The OHSC is included. Here's the current description from Martin's site'
D-18 Authentic 1937 5 out of 5 Customer Ratings $7,399.00.
1937 was an excellent year for guitars with a perfect storm of craftsmanship, innovation, and materials. This Authentic Series replication of a 1937 D-18 stays true to the original with hide glue construction and historically accurate detailing. This guitar features genuine mahogany back and sides and an Adirondack spruce top, and it includes an Authentic circa 1937 bracing pattern. It includes period-correct "18" Authentic-style appointments and an Authentic neck barrel and heel, and new this year, a more accurate body profile based on dreadnought shapes from the early Golden Era of Martin’s history.
I will be adding more pictures shortly.
