The motors usually turn out very well when cleaned and greased. You have the version I like the most, with the art nouveau decor on the plates and gold decals (well, they are all very nice). The chromed parts clean up very well with a metal polish, so does the needle and pressser bar. For the body I have used resin type car polish, even after cleaning it lifts up dirt and shines up. Be a bit careful with the decals, but with polishing once or twice a year or so it is more protected.
