I'm like you Brett I love looking through the old magazines and brochures at stuff like this. If you got that one recently I was probably bidding against you.

It's a nice brochure, thanks for sharing.
Can I ask how you know the Brochure is 1968, does it have a date?
I have a feeling that often the cars that were photographed for brochures where the same cars being used for the road tests in magazines etc, so they occasionally may have differed a little with add ons like that. I think the sight tubes were an accessory, they probably got added to the car at some stage.
The tricky part is often the cars for the brochures are pre production prototypes so they differ anyway. A good example is the white Cooper S rego DLD 322 that appears airbourne on the cover Wheels magazine in August 1965. If you look closely its the same car used for the photos in this Brochure for the S.


Note this car has totally different plumbing for the heater and the crankcase breathing, and the brake pipes are all rough and hand bent. Even the Wheels article notes it's a prototype car.
Another car that appears in lots of road tests is a dark (black?) Cooper S rego DXK 522. I'ts in at least 5 different magazine road test that I've seen. There's a few good shots of it's engine bay, It's a little more standard (below)
Don't forget over the life of any of these models there were lots of little changes e.g hose clips, plug caps, starter solenoids, heater taps etc. etc.
Note also that when they resprayed the motors in Australia they just sprayed the oil cap too

, I've seen this a few times.
