I checked my library of stuff, and to my surprise found that I had picked up the first year 230 SL Owner's Manual. This manual is part 113 584 01 96, which I take to be the first version - the "01". There is no picture of the spare tire mounted at all, either vertically or horizontally. The next manual I have is for the 250 SL, 113 584 08 96. This manual does have a drawing of the spare tire and it is shown as horizontal as is correct for the 250 SL and 280 SL. (and later 230 SLs). I am assuming that there were manuals numbered "02" through "07" for the 230 SL, but have no data or examples to support that.
There has been discussion on the forum about the owner's manual numbering.
Here is one thread
https://www.sl113.org/forums/index.php?topic=31601.msg229195#msg229195 It includes a reference from MBPaul, who is the original owner of a 1966 230 SL that came with the 113 584 01 96 manual
Note - the spare tire was changed in the 1964 run, VIN ending in 6069 was the trial car, then put in production at VIN ending 7205 except for 7216, 7232, 7253, 7277 - as noted in the change list from Mercedes Collector and published in Pagoda Notes Vol 10 no 1.
There are a number of changes made during the 230 SL, so there may have been updates to the Owner's Manual to reflect those.
When looking for an owner's manual, the early manuals, at least through the 250 SL, if original will show the dash and instrument panel in full color. The reprints are usually in the same blue print as text.
