Classify these Igorots/Cordillerans from the 1940s

They look Southern Mongoloid like the Mentawai or Dayak. Taiwan Aborigines also look like this I think.

They look different from Amazonians who are much more stocky and have bigger prominent noses and robust facial features. These Igorots despite looking fit still look much more lean and not as stocky and robust.

I don't think they look like us
