SAKWiki mentions that, quote:
"Some 1970, and 1975 models were produced with Red Alox scales (Silver also available)."
Possibly this happened for some 1976 Soldiers as well. The scale cross matches the 1976 year if I am not mistaken, but I am far from an expert on Soldiers.
On the other extreme I won't exclude the possibility that somebody just painted the scales so it may look like worn out anodizing. But the wear appears uniform so likely it is indeed anodizing in this case.
If you will buy it please tell is what it is after you will receive it
