He is wearing a US tunic, but since you found hiim in MEX, you might want to check his markings. If he has a black pelvis and 'scrubbed out' marks on his back he is a Cipsa ape made in Mexico. There are folks that would probably trade you a near complete US version for that guy if he is Cipsa. (myself included).
Fun score and congrats o your new ape family members.
