This is a good discussion and gets the old brain cells working well!
Although I've had copies of those Jack Daniels photos for a while now it is only with this thread having been started have I gone back to them for another look. I've been looking at the instrument panel in particular and have zoomed in to see what I can spot. Have a look at this:
Look at the two gauges at the bottom of the panel. I think the LH one is oil pressure and the RH one is an ammeter. That would make sense as none of that information is available in detail from the speedo dial area. What I am curious about is the dial to the left of the instrument panel. There's a needle and some figures but what could it have been for? Remember it was just a single engine.
You know you could look upon this vehicle as an Ant in sheep's clothing! Put it another way it was an Ant test bed. I'm sure that the engine and drive train were what would soon go into the Ant. Note too the larger wheels although not the same as would be fitted to the Ant. Were they not Austin 1100 wheels that they used on the Ant?
Spider, in answer to your comments:
Prisoner style windscreen mounting. This would make sense if we are talking about a 1963/1964 bodyshell.
Sliders on an unusual driver's seat - it almost suggest someone(s) did quite a few miles in it. I did try and work out where this seat was sourced. It's certainly a very old style of car (or van?) seat. The nearest I could find was something similar to that as used in an Austin Seven! Could it have been from an Austin sports car seat from the early 1950s I wonder?
Where's the fuel tank? I see a hole for the cap but no neck or cap? I agree and think it goes where we see the hole. They probably hadn't fitted it at the time the photo was taken. In any case if it didn't go there where else could it have gone?
Rear seats but no passanger's seat, I'd guess because the driver's seat does appear proper width Have you noticed where they fitted these two seats? Virtually up against the back panel. Not much room for anything behind them! I'm not sure why they fitted them so far back.
Hard to make out but appears the gear stick comes up from a remote type location? I agree. If the engine was canted as it was for the Ant the gear lever position would have needed to be re-jigged to allow for this
The body also does appear to be a production one, rather than the usual prototypes normally associated with the experimental vehicles. As I implied earlier this Moke was being put together around the time that the production Moke was about to be or had just been released.
It doesn't seem to be road registered at this point. I can understand it not being registered. If the US Army was evaluating it they are unlikely to have driven it out on the open road. However it did have a US Army number painted on the bonnet
A final question. What were the various switches for on the instrument panel? Choke bottom right?? Lights top right?? Panel light top left?? There is a sticker (unreadable) on the top of the panel on the LH side.
