I have a complete set (front and rear) of cylinders for a Twin Wasp 1830. These cylinders are in perfect/NOS condition. They still retain the original factory paint also in perfect. They have never been through overhaul and are factory fresh. The bores, seats and guides are spotless. I would have to think these are just about the last complete set of NOS cylinders anywhere. The story behind these cylinders is pretty neat! I have them listed on Trade a Plane, please refer to the link for photographs. Please ask any questions! Thanks for looking!
