I had a mule deer tag and the tail and the rest of the animal were pure mulie; ears, tail, color and all. I don't know enough about the tarsal glands to have told the difference and they are gone now. I will gall Jim at the Tucson AZGF and send him the pictures I have. The head and cape are at Sievers North Mountain Taxidermy in Phoenix. Frank at Sievers indicated he was going to contact the AZGF as they are always interested in weird stuff.
The deer was absolutely clean; a healthy specimen. (I just finished a bowl of back strap chili with my wife. We agreed it is better than elk.) There was no obvious damage to the left antler socket, but it did face forward. In another year this guy would have been in pain as the last two tines rubbed his nose and jaw. I did him a favor, but not one the two does with him appreciated.
Thanks for the response. I'll let you know what I find out.
