They're an interesting bit of kit, roughly equivalent technically speaking to the '66 Renault 10 I once owned.
Stylistically as well - there's quite a few cars mashed in there. To start with, you have the front which resembles a squashed series one Corvair. Then in side profile you have the upper glasshouse and rear deck which resembles a Dolomite. There's even a Hofmeiser knick in the shutline and vent that follows the contour of the C pillar. The rear intake treatment looks cribbed off an S series Skoda.
It's really interesting how the front bonnet for the boot opens like a front engined car - on the 8, 10, Dauphine, RE Skodas and Fiats they all hinge and tilt forward.
It looks like an Australian market brochure, judging by the NSW number plates (I have one at home, they're very solidly made and pressed out of amazingly thick gauge steel!)
This is the thing I find fascinating about Japanese cars of the 60's and 70's. They certainly weren't innovators in terms of body design, but they were very clever at adapting establish house features to local tastes.
Did any make it to the UK? Were the engines their own or were they bought in? They must have built another company's lumps by license surely - they made trucks didn't they?
