I've done quite a few Euro mounts, but this was the first moose, one that my step son killed with his Tribal North Half tag.
Moose skulls, due to their physical structure provide challenges not seen with other skulls. First you need a real large tank, as in a small stock tank. Then with the antlers exiting the skull on the sides, it prevents using peroxide in the water bath to help clean and whiten without bleaching the antlers. Baking soda, Dawn dish soap and lots of cutting, scraping, picking, tweezing and pressure washing, we were able to get it clean. Used the hair gel peroxide brushed on the skull for 24 hours and then rinsed off to whiten. Now it just needs the Skull Hooker attached for the finished product.
