So the donor car is becoming interesting? The guy I bought it from definitely thought it was a 1970, and it was advertised as such. No problem though.
Like many Landrovers of that age, it has had significant modifications through the years!
I removed the steering wheel today so I can see if it'll go on my DeeDee. The main activity for the day was trying to fit my better 7.50R16 tyres to as many of the 272309 wheels as I have. I did discover that under the paint of another wheel was the correct part number so I now have 3 of the 272309 wheels correct for the S2a and 6 of the 231601 correct for a S1, although only three are date stamped to be correct for my early 1950 S1.
Note that the distinction between wheels is not the age but short or long wheelbase (although at the time of your S1 there was no lwb). Also, the 272309 was optional for S2a swb.

So, onto some of your observations:
The extra gauge in the dash is a smiths combination oil pressure and water temperature gauge.
This is actually the gauge that was an optional extra on this model (standard on diesels, at least in Australia) - but not in that location except in Australian military 2a Landrovers. Normally installed in a small panel to the right of the instrument panel.
Funnily enough there is a water temperature gauge also fitted to the extra dash panel nearer the steering column. I assume this is the standard one and the smiths one is an aftermarket later addition.
This is an addition as well. Landrovers up to 1967 had no temperature gauge fitted as standard (always thought this was a serious shortcoming). Also, the extra panel is steel - the optional Landrover one is aluminium, and pressed to match the main instrument panel. I am guessing that the temperature only gauge was added later after the capillary failed on the combined gauge - and the single gauge was a lot cheaper.
The other main gauge seems to have been "fettled" as well. Should the fuel gauge be at the bottom even with the "FUEL" text at the upper right section?
No. The fuel gauge and main beam warning light have been swapped in position, and the fuel gauge is not out of a Landrover - colour is wrong.
... and yes, I also thought it funny for the speedo to go to 100mph in an old Land Rover!

I was going to make a comment about it in my yesterday's post.
Again, the speedo is definitely not out of a Landrover - all Landrover Series speedos were simple white on black with a white pointer. I would guess that both the speedo and fuel gauge are replacements sourced from a wrecker, and probably came from some other contemporary English car which also used Smiths instruments with a similar layout.
While poking around under the bonnet I cleaned up this label:
I assume this means it was originally delivered in Perth.
Yes
To wrap up, you noticed the oil breather pipe.
I haven't seen one of these before. Does this allow the crankcase to breath independently of the rocker cover breather? The breather pipe does a big arc of the motor and then down the passengers side to hang down the crankcase beside the sump. I don't think it has any sort of cover over the end, but might have something inside it. I'll get to that one day.
It originally had a small oiled wire air cleaner on the top of the oil filler, similar to the one on top of the rocker cover. Between the two, they allow crankcase ventilation, helped by the draught from the fan. This setup was replaced in the mid sixties (in Australia) by a positive crankcase ventilation system, that saw the roacker cover fitting venting into the elbow on top of the carburetter, and the filler pipe fitted with an airtight cap, with a tee off it to a positive crankcase ventilation valve next to the carburetter connected below the throttle valve. And no, I have never seen anything like yours either - I would guess the engine had developed so much blowby that it was chucking oil out the filler vent, and the owner added this contraption to stop it getting all over the distributor etc.
