I agree with JohnTheTexan, hard to tell from that picture.
I would guess it's a TGLB in tanker grey and black canvas handles.
Definitely not a TG14, those were satin, saber ground with a swedge and no fuller.
The “ManPaddlingPork” was my INFI pusher as well. He and a few other Hogs had a Chop-In at my place years ago, I’ve been hooked ever since.
I’ve met some of the finest people I know through Busse knives. Looking back, I know life has been sweeter thanks to Jerry and his crew...
I suggest getting some Zip Strip, use it outdoors or at least in a well ventilated area. Warm the knife with a hair dryer and pour the Zip Strip on liberally. It will take some time, Ceracoat is tough stuff.
Just a heads up, some people were finding TigherHide micarta under ceracoat.
