Canada 1 cent 1937-1947 Alloy inconsistency [opgelost]

There is the article
https://en.numista.com/catalogue/pieces435.html

It states in the Comments section

Alloy 1: from 1937-1942; .955 copper, .030 tin, .015 zinc
Alloy 2: from 1942-1952; .980 copper, .005 tin, .015 zinc

and in the year list:
1941 Alloy 1
1942 Alloy 2
1943 Alloy 2

Where the data should be corrected?

For example, my catalog states 1942 Alloy 1 only.

Done, thanks.
