The owners manual is the most difficult to find. Here is one on eBay right now:
eBay item number:354442830510, but note that the illustration for the dash dials is not in color, so this is most likely a reprint.
The parts book would be Edition C, 12126, these come up from time to time on eBay.
The other items are detailed in Pagoda Notes and are not specific to the 113. I assembled a full set by keeping an eye open for the various other items.
If you go to the tech manual, scroll down on the first page and there is a link to all the issues of Pagoda Notes. Issue 2 vol 3 details the literature for the car. As a side note, Issue 2 Vol 4 shows a number of the other items if in-period literature for the car (sales brochures and the like).
