Wow! What a fantastic looking buck. Well worth a head mount. If he only save the antlers, he can inject embalming fluid into the veins of the velvet. I have done this three times over the years and no problems. All are over 20 years old now. I have used less than 1/2 pint for the three. I still have the rest (8oz) you can have, also needle.
Good fishing to all. Hue
