GGR,
I have a late 250 SL, european version
no tinted glas, no power steering , no headrest; door trim is a mix of 230 and 280 ; the chrome is like the 280 and the arm rest from the 230 is there.
No defroster in HT. THere is also no defrost indication on the escutcheon from the heater levers.
if you need to know more, let me know, I will be happy to upload detail pictures if you like.
Regards
Pascal
