Looks Original to me, have seen many of them (and similar ones) on different Flea Markets around Solingen and on german Ebay (maybe not visible for international Users). The Gold Wash and the Etching looks good and fine made, the Box is made of Plastic and one of the Later Boxes that had been made since the early 80s i guess. The Made in W. Germany is maybe an indicator for a pre 1991 Razor but it could be that Dovo used the W. Germany up to the mid 90s or longer. The Scales are just the simple Dovo Plastic Scales like they use even today on their standard Razor.
Its a good Razor, im sure after its honed well, you will be satisfied with it :-)
