From Mercedes Germany and the Global Mercedes Collectors forum, it was confirmed that the Tail fin I posses is a W 201. ( Everyone asked for Engine & Chassis number before it is confirmed that she is 201)
I also agree that many in Pakistan & India know that shape as W 115.
I happen to know Mehmood saheb (late) who was Merc King in Karachi till he died in 90s'. His workshop was opposite CAFE De Khan on Tariq Road Karachi.
He was USTAD to 2 NUT cases who were MERC crazy as him. Khalid & Rafiq. Khalid possibly from Norther Areas, fair complexion a heavy built 5ft 6" fellow and Rafiq dark complexion under five feet guy.
The number for Khalid is OFF I will try and get hold of him agagain sometime.
Anyone who can help me trace - Rafiq?? Please
