This is a complete box of nos 4cyl B-6510 in original box . The condition is new but some light surface rust ish on the outside but brushes off and inside nice and clean . This is nearly 100 years old and a rare find and have had these for 30 years on the shelf. I’m not going to build a banger motor and going to stick with my flatheads. I’m looking for 50 plus shipping thank you
