Whilst everyone is reaching into their archives for owners handbooks, if one for an S turns up I would be interested. I have a DG copy of a 76 2500M in use as a substitute at the moment which would become available.....
Dave, you took the words out of my mouth. I have a parts list also but a Handbook would be very welcome. I don't think Workshop Manuals ever existed, that would make things too easy;)
My 3000S came with a 3000M handbook, as Frank says. I think mine could be the original by the state and look of it. If I open it another page usually falls out, it's that bad. I think you can get a new one from David Geralds.
