Very rare and very good condition for 170 years old. Parchment is in excellent condition with obvious signs of age but certainly not delicate or rotten, still rolls up and unrolls nicely with no rips or stains. Machline ware cylinder is in good condition also with no splits or cracks, still has original label in superb condition, cylinder box does have obvious signs of age as you would expect.
Very nice piece of history with nice obvious dating. Very collectible lovely piece.
