Buckstix, only two of your photos show Muntiac, the one at bottom left and bottom row middle/top. Muntiac have large facial glands in front of the eyes and the males bear small antlers on top of long skin covered bones. their tusks are smaller than those of Musk deer. Most of the photos you posted are in fact several subspecies of Musk deer. As neither the characteristic glands or antlers of Muntiac are shown in the engraving,but very prominent tusks, it depicts a Himalayan Musk Deer, Moschus Leucogaster, native to northern India too, IMHO.
