Set the meter to the lowest resistance range - usually 200 ohms - and measure across the terminals. If it’s an 8-ohm unit it should read about 6 ohms.

Thanks for this @ICBM I tested it today and it is the tweeter for sure. Should be able to find a replacement but one day will have a look inside to see if I can repair it.

These ones have a metal domed back and are 16 ohms, which seem to be less common.
The date on the bass drivers is 6 Nov 1979 so they could probably do with a recap I guess?
Interesting that the front panels are bookmatched. These are hidden behind the speaker grille, yet they still matched them up.
It's less of a veneer, and more of a cap being 5mm thick.
The HF1300s seem to be usually described as tweeters, but they're clearly midrange drivers here since the actual tweeters are the small domes.

My understanding is that the HF1300s are tweeters, and the drivers above those are Coles 4001 Super-Tweeters which come in around 14kHz.
Despite the online doom about these early original versions with the white surrounds cracking and splitting, mine appear to be still in very reasonable condition and certainly sound good.
Is there anything I can do to clean / maintain / help to keep them flexible to give them every chance of lasting a bit longer?
I'm not even sure what the material is.

I'll take your advice and cover them up.
