If we're talking about the yellow car in foreground, an Australian built 1966-72 Morris Mini Moke / 1973-81 Leyland Moke? Are these taillamps the ones of the Leyland version? |

Definitely Aus build with bigger wheels than UK, and as far as I can tell, yes - Leyland lights. YDO18 as no obvious Californian trim bits. |

I thought it was just Leyland Moke, without Mini? |

Depends who you believe - it seems to have been one of those floating changes which may or may not have really happened, and there are inconsistencies at some points between brochures/adverts compared to grille badging. Another version says 1968-69 YDO8 (10" wheels) was Morris Mini Moke, then everything with 13" wheels was Morris or Leyland Moke [YDO18 and YDO30 for the Leyland-only Californian edition], unless it was the 71+ Morris (export) version which was Mini Moke. I don't think there is a single consistent history, so simplest solution is to keep everything as Mini Moke |

About the model codes, according to The BMC Experience: • 1966-68: No specific code (did the UK/international model have one)? • April 1968 - March 1969: "big-wheel" [YDO8] • April 1969 - 1982: Mk2 Moke (1098cc engine and full-synchro gearbox) [YDO18]. • December 1971 - early 1973 : Special Export 'Californian' Moke [YDO30]. All other Australian Mokes that followed, including the September 1977+ Californian models, were variations of [YDO18]. -- Last edit: 2016-02-06 00:08:45 |

My main source is this book, which has detailed listings of what was built and when at the end. UK-built Mokes were always only 848cc, and I don't know of a specific UK ADO code apart from the generic early Mini ADO15. Digging deeper online it seems Aus assembled CKD kits from UK from 66-68, which I assume retained same 848cc engine, and were coded YDO7. When Aus production started in 68 using the ex-UK tooling the 1098cc engine was fitted from the start, therefore a new code assigned [YDO8] and for the first year it kept the 10" wheels. The upgrade to 13" wheels created YDO18 and survived through 1972 Leyland renaming to production end. "Californian" Moke was trim package aimed towards export markets, but also incorporated 1275cc upgrade and assigned YDO30. So coding means YDO7 = 848cc CKD from UK, YDO8 = 1098cc small wheels, YDO18 = 1098cc big wheels, YDO30 = 1275cc (always big wheels and unique to Californian variant). If 1098cc Californians existed (which is unlikely on present evidence) they would be YDO18. I have seen a very faint reference that there were a few very late Aus Mokes with 998cc but no details or code given - if this is true it might be a late running change to replace the use of the 1098cc - there are parallels with other BMC assembly elsewhere eg final Authi ADO16. Also worth noting that 1098cc versions of any Mini type anywhere in the world are very unusual - Aus seems the only country to have really done it, both for Mokes and their mainstream Clubman-based Minis. The only other examples I can think of were UK Clubman and Clubman Estate 1976-80 (manual only - the automatic stayed with 998cc) which then reverted to 998cc as the 1000HL estate when Clubman saloon stopped. Plus the 1977-80 1100 Special edition (built in Seneffe for UK and Europe). So maybe they stopped all 1098cc production at that point (1980-ish) across the world, forcing the Moke down to 998cc?? Overall, I think we're OK with all Aus Mokes as they are, except we now have the 66-68 CKD assembly as YDO7 to factor in, which threatens the reliability of our YDO8 batch unless we can find visible clues to split them; all our current YDO8 are post-1968 film appearances, and my guess is Aus would have more fully-produced YDO8s than CKD YDO7s, but .... |

I don't really like relying on a single source, all the more when it doesn't really match what is said in several others, including Australian and UK ones... |

Update: Aus emission laws killed off domestic approval for 1275cc in 1974 and 1098cc in 1975, so all domestic (ie sold in Aus) Mokes became 998cc then, which almost certainly meant a new code - currently unknown - to replace use of YDO18 and YDO30. And this would apply to 1977 Californian relaunch in 998cc form. But it also seems 1275cc was re-adopted late 1979 until production end in late 1981. |

But the other sources are not particularly consistent between them from what I can see, and do not have as specific a sequence of the name/code changes. Even with the book, things get peculiar after about 1975, but up to that point I think the book has the most complete sequence and is logical in that code changes were applied for each mechanical change - other sources mention mechanical changes and some of the codes, but do not marry them particularly well. What the other sources can add - which my book does not give in any depth - is visible detail changes to things like lights or bodywork so we can improve dating. As a result of tonight's exchanges and your links, I think we can pin down new bigger rectangular front sidelights - which I've never been able to date before - as 72+ accompanying the Leyland rebranding, and maybe the bigger rear lights (as this one) to the same facelift. |

The pictured Moke was built between 1977 and the end of 1979. The rear lights, fuel tank filler location and spare wheel mount provide the references to its age. The seats are non genuine and have been replaced at sometime. Australian Mokes were only fitted with 998, 1098 and 1275 engines in A and A+ variants towards the end of production in 1982. Never fitted with 850's. 1098 were fitted up until 1974 when the Australian British Leyland Motor Company factory was closed. 1275 engines were used in only in YDO30 between late 1971 and April 1973 and then were re-introduced in 1978 when the engine and disc brakes were also fitted to the LS Mini. The YDO18, and YDO30, was the Australian Drawing office code that was used up until 1978 when a global change to how Leyland identified their vehicles saw the model number become part of the body/VIN numbers so there was never another YDO code issued for the 1978 and 1979 models that some could the 'facelift' models. |
