For those who are interested:
I purchased from the MB owners club in the uk a reproduction manual for 230's 1963 - 1968.
It's abit like a Haynes manual.
Handy for day to day stuff I think and probably worth a look
Published by Veloce Press and is a reproduction of a book published a while ago
Anyway for your reference:
ISBN 1-58850-030-6
It was £17.95 inc post and packing in the UK
Thanks to everybody re help with the BBB from MB USA. I will probably take you up on that at some point
Cheers
Malc
