123 ‘Citroen’ designated distributors come with a pre set selectable curve’s and cover the Perfo, 11D, HY, DS etc. etc. engines Roger.
Now in my other recent posts on ‘ethanol’ you will see pics of a burnt out valve from a Perfo engined Traction which was actually running a 123 electronic dizzy set for a Perfo Advance curve which looks a bit like the picture in your 1st link.
I took that distributor out a couple of months back as I wasn’t happy with the way the car ran and replaced it with a Ducellier manual dizzy copy (by Valeo) from Renel https://www.renelauto.fr/allumage-electricite/338-allumeur-adaptable-neuf-avance-a-depression-pour-traction.html for 65 euro
Even with the low compression on cylinder 3, the car started and ran better with the ‘old fashioned’ dizzy so it will be interesting to see how the car performs after the head rebuild, which will hopefully be by the backend of next week….
BTW here is the selectable ‘curve table’ for the 123 to see if it helps you
