I always hated it when people would top up the fluid as routine maintenance because the reservoir volume is calculated to be LOW when the brake pads were worn enough to allow the caliper pistons to have enough fluid displaced to cause the level indicator to illuminate.
If there is NO LEAK and the level indicator comes ON, then a brake pad change is required!!!!
I'm sure the engineers spent time to calculate this and NOBODY uses this logic.
Even when I replace the fluid in the system I try to put the level at the same point before I drained/flushed/replaced the fluid. (recommended every 2 years)
Just me thinking out loud.

Green? That's not good... Either your car has very very old Castrol-Girling Green fluid—which I think would have been the factory-recommended fluid in '73—or the fluid is so old contaminants have turned it green.
To be safe I would flush the system entirely with new fluid, rather than top it up. Castrol-Girling Green was replaced by their Amber fluid in the late 1970s, a.k.a. Castrol-Girling "Universal" fluid; the Universal fluid is what's spec'ed in my '88 Series III. The modern equivalent is Castrol DOT4, but really any DOT4 fluid should do.
