I am agreeing that it is a repaint. According to Nancy Johnson-Strebo's book, Featherweight 221-The Perfect Portable it is possible to repaint a featherweight with special crinkle finish paint available from auto and machinery suppliers and apply decals in the appropriate places. She does mention that a genuine black crinkle machine will have two sets of parallel grooves on the bed and arm extension always be a series AF machine and be a Model 221 SV 1. If you love Featherweights, you must have her book.
