When I started my Acro project in 1974 I was not aware of any kit number for my plane. I have gone through all correspondence from Jim Osborne and there was never a reference to a kit number for the plane. There are many kits that make up the Acro but I have no serial number for my plane. Even the numbers that reference the various kits only refer to the invoices on which they were billed. I suspect that any planes with serial numbers were for a factory built plane. Only planes with serial numbers are required to fill out a Bill of Sale. Am I wrong?
