The end is in sight. For whatever reason, my sleeve kung-fu is strong. They look short in the picture, but mid-18th century cuffs tended to be large, so the sleeves ended right above the wrist joint.
The arm openings are rather large as compared to later in the century. I decided not to line the sleeves, since the coat is heavy already. All that is left is to finish the neck opening and turn all the body lining seams and back stitch them. Next time, the finished product.
