REEL #4 1946
Apparently this is Version 3A. Certainly the
change in body shape from a rounded dome to a flattened dome
constitutes more of a change than that between Versions 1 and 2 where
only a couple of knobs and the spool were changed. The next reel after this one, the one where anti-reverse was
introduced, is commonly known as Version 3, so it would probably be correct to call that reel Version 3B.
