It's referred to as the:
Nissan Publication Number "C-0030R"
Datsun 1200 R-Drive PARTS CATALOG Model B110 SERIES. About 800 pages double sided, foolscap. Printed in Japan in English.

I've got a Factory 1200 Workshop manual too from a year ago.

I got it from an Datsun fanatic in Christchurch via Ebay. I bought some other 1200 parts off him, and I asked him if he had any other 1200 bits.. It's a bit tatty and used, I had to pay US$50 for it, but I guess when things are this rare, price is hard to judge. Every Datsun Service Dept would have had one. But I guess they probably got thrown out over the years..
