Pretty certain it's a 1" headset. I can check my CR1 tonight if need be, if I can get to it!
That headset is on eBay:
And the outside dimension in description (30mm) pretty much matches the inside of your steerer tube you mentioned. Again pretty sure these only came in 1" flavour.TANGE FALCON P.5000 S BLACK HEADSET - NOS | eBay

Somewhere on RB there is a thread with a scan of the spec sheet of the parts...
I’m measuring the inside diameter of the headstock and taking that reading as the headset size. I’m now thinking / realising that the 1 1/8” refers to the size of the steerer tube, not the headstock inner dia.
Or am I still barking up the wrong tree?!!
