Lovely brass base to the fittings as well, forgot to mention that earlier. A sign of really early quality as you already know smile.
Yes, have pictures of a slant Henckels on file ( may very well be VB's Henckels pre-purchase ) with huge "19" numbering to the blade tang.
Great touch with the acorn spacers to the pommel detail, some early Wingen pommels also have a similar addition.
