Hi Mark
You would seem to be the possessor of that rare item a Seven dynamo in good shape. The windings are not cooked black, solder not thrown, and windings well secured with varnish.The marks on commutator suggest brushes may not have been contacting properly. Perhaps the comm has been cut down so far that part worn brushes do not reach.
