Boar heads

As my nascent sculpting skills currently suck, I'm trying to find a pre-sculpted head for my in-progress extreme War Hog. I like the original one (see below), but it's looking a little tiny now that the conversion is growing.

It's looking like I need the boar head to be about 3 cm in length by 2 cm in height (roughly, though I can probably fudge a little either way). I've found a few so far (see below), but I'm either unsure of their scale, not completely happy with the look, and/or unwilling to pay that much money for a resin head when I'm unlikely to use the rest ...

Does anyone know of any out there that might work? Or does anyone have one of the above models that I could see to check scale? Thanks!
