Most of the current fake stocks have the "Made in Canada" and SAL 1944/45 markings.
Many real stocks do not have either the "SAL" or "MiC" of markings either.
Like yours, I have seen a number of original stocks without the "made In Canada" stamping, and sometimes when it is present it's location can differ as well.
None of the fake stocks have the oval inspectors marking shown in your first picture.
...yet...
