Incidentally, this inspired me to look up information about the

the
information that the alloy Anibal was a steel alloy with 44.4%
nickel.

Do you still have the URL to that web page? I'd like to read it.

Not the same webpage but Guillaume's Noble Prize speech is online:

https://www.nobelprize.org/nobel_pri...me-lecture.pdf

The ultra compensated balance wheel using Anibal is mentioned in passing
towards the end. Invar and Elinvar get pride of place in his main talk.
(Anibal is a sort of compositional tweak of Invar)

Poor old Anibal alloy is lacking a Wiki entry or a mention in Nickel
Cobalt & their Alloys (that I can see).
