Books are helpful, but using a book does not guarantee originality. And I tend to look at the quality of the work as compared to originals. I also look for signs of age, or if an item might have been refinished. What I am seeing with the new images still looks like something that could have been re-plated. But that is only my opinion from what I seem to be seeing in the images, and "in hand" inspections are unquestionably better. That said - the logo still looks like it�s �washed out� (as compared to the etching). And if the backside of the handle in person looks like it seems to in the image. I would be concerned, and would be looking very closely for other signs of reworking/refinishing. The question being: If plating is damaged by use it usually exposes the base metal. But if the plating fills in or covers over damaged or worn areas it�s probably reworked. FP
