Honestly Phade,
I had a friend arrange the work for me. Although I know the individual that did the work I did not get a chance to talk with him so I am not 100% certain as to his procedures.
The guy that did the work is an associate of a world class taxidermist.
Therefore he has made an arrangement with his employer to accept additional work only if he does not handle anyjobs from customers that have previously worked with his boss. (My friend does the job for me much faster and cheaper than if I had to go through the shop)
Knowing the size and scope of the taxidermy shop he works for I am sure they have a large colony of beatles.
As for the darkness of the antlers. I believe he may have slightly darkened them in the mounting process. The rub marks are absolutely identical to how they appeared when I shot the buck, however to my eye they appeara few shades darker.
I will try to find out if he did in fact use any process that would have darkened them.
Here is a picture from the day I harvested this buck..
