I have to confess, understanding the potential strong opposition may come to this from the purists, to get for my 1970 280SL the box design generally believed to be proper for W107. I have been looking at dates and models of various car makers as well as the Hartmann items not assigned to any car make and concluded that it might be likely that Hartmann changed the design to the one we know from 107 in the beginning of the 70s. Then Mercedes would use what came from Hartmann, I think a long as it fit the holder.
For 1968 I would use the blue design as Bob is looking for. For earlier - the green design. But that is just my theory.
Waiting for crashing responses

And if there are facts in those responses - I will go and buy the blue one or look for the green one (this one is rare).
This is a bit like the carpet type used in various years - lots of discussions on this. Until I talked to an elder member of Mercedes Benz Classic team in Essen who worked for Mercedes in the 60s. He said: "even if the general type of carpet in given year was a newer one, if someone ordered a colour they had older carpet type on stock - they would use older carpet type. Some colours offered never changed the type of carpet to new one."
