Dear Friends,
Very good observations up to here.
Alfred, Scott & benzportland are correct. Only the flat style slanted sunvisor clips are correct for the 230/250 SL up to serial 002979.
The old ones that James had in his white 230 SL are not correct. Either 280 SL or /8 sedan or anything else.
The new replacement is also not correct - sedan style as you mentioned.
The clips that came off my parted-out 1963 230 are clearly the solid type, not more really grey but they have faded to a more tan color, are very brittle and almost like solid rubber & have the 113GHE embossment (GHE = Gebrueder Happich, Elberfeld).
The ones of the '64 are a little different, not solid but hollow and have the metal clip inside.
Alfred is right, the number for the 230/250-early part never changed, still these are "variants" (this is the case for many parts where the parts number never changed ... e.g. ashtray).
I have a few of these clips flying around anywhere, most are old. I will check them again the upcoming weekend...
But I am confident, there are no additional findings to what we already have here.
In summary:
230 SL/250 SL up to serial 002979:
one part number (113 811 0140), two different versions:
Old style is solid, newer style is more plastic, nonsolid but with internal metal clip.
Then there is the later style 250 SL late/280 SL clip (113 811 0240)which looks more (ore identical?) to James old ones.
Best,
Achim
