It is indeed a bit difficult to find I will change that in future to be more easy.
It is a pdf file to be downloaded, but the link is somewhere in the text and only visible because it is blue.
This should help https://www.wdnorton.nl/Electrical_equipment_page/Article%20Nife%20C105%20issue%202.pdf
But be aware, this still is the old version in which I made the incorrect remark that Lucas C105 Nife was a Nickel Iron battery instead of a Nickel Cadmium battery.
I will send you the correction I wrote for the VMCC by mail.
