Right away the AD tells me that it was one of the earlier models and it was made in the U.S. A serial numbers were made in the New Jersey plant in the U.S.A. and models with serial numbers beginning with an E were made in Europe (Clydebank Scotland). Some later model featherweights ( 1958 or so and newer) had the model number 221 or 221K for example on the front near the Singer seal but the earlier versions did not.
