This notebook measures 8 x 6 x 1/2" and is something around 200 pages. I have no idea of the vintage.

Cardboard cloth covers with "Porsche" in recess on the front, the covers are grey.  The first page has the Porsche crest, the rest of the pages have dots for demarcation, and there is a page marker built into it, on the whole it looks and feels high quality. 

Condition is new in the wrap, I don’t know the history of these, I suspect they were used at Porsche Service School, but I don't know that..
