Looks like a spark ignition electrode, but if you're sure it's the
ignition detector, then within a flame there's some ionisation

I thought ionisation detection was a more recent method than as long
ago as 30 years? The common method back then was the thermocouple
method of flame detection.


Fecking hell. How many time do I have to say that its NOT a thermocouple?
Ive owned and serviced this machine for 30 years now. I DO know the
difference.

Year of manufacture.
