Unfortunately, we cannot learn anything from Chestnut serial numbers - no records are known to exist.
To get started, post the length, maximum beam and depth, whether it has 1-1/2" or 2-3/8" wide ribs, whether it has carry thwarts, and if the decal is still present, what city is printed on it. Also if the decks are heart-shaped or semi-circular.
If you can also post a photo or six, all that much the better.
