To me it's a multi-faceted question. #1, is the engraving original? If not, was the sax re-lacquered prior to the engraving? I am not a student of the Balanced Action and Super Action so the engraving just looks odd to me. So I didn't concentrate on the engraving - I was looking everywhere else for evidence of buffing after the original polishing. Don't forget, every lacquered or plated sax (with a glossy finish) is buffed before lacquering/plating. Others may be media-blasted to get the matte appearance. Anyway, about the only things visible are the 'chain-link' trim and the Selmer logo/address area. As near as I can tell, it has not been buffed since manufacture. This would indicate that the engraving was done at some time after the original lacquer was applied. Someone who has studied the saxes of this period will have to judge if that is Selmer engraving from the correct period.
So that's the engineering and legal boiler plate. To me, the sax looks gorgeous and I would definitely love to try it out. I think anybody getting it will be glad they did.
