The gunstock w/ 'jackass' shield is one of a few made by GEC for Charlie Dorton. I used to have all three models, the 76, the 72 and the 65, but I sold the 76 and 65 off to fund my knife store.
As luck would have it, I found another 76 (pictured) not too long ago and snagged it! Wish I still had the Hogan though...
How about a custom 're-work' of an existing GEC, this one a popular 85 pattern clip/pen modified by ESNYX Custom Knives in Sarasota FL.

Evan replaced the covers with some of his own hand-jigged bone, put on a custom shield and made it work slicker than whale s***! It is one sweet knife!
