No pix from me I'm afraid....
But, I do have both knives and like them. They are rather different from each other, so let's consider some aspects. The CASE has a narrower body and a much narrower Master blade - a Clip (Turkish slim type) rather than a relatively broad Spear on the GEC. The secondary blades are completely different too, Modified Pen v Coping. The GEC has nail nicks both side, I used to think this better more Old School but changed my mind on this, I prefer turning the knife round to open the secondary, just habit. I assume you're after a Barehead Eureka, because weight plays a role here: CASE 65g GEC 77g a double bolster GEC will be heavier still. The GEC is a bit longer than the TJ and has a much different handle, very comfortable in hand. The Barehead is also all steel so it requires more careful maintenance than the NS and brass lined CASE, the double bolster GEC is brass/NS though. Half-stops on the GEC, I prefer not to have these, but the pull and W&T on both knives is smooth,good.Wish I had the Ivory Bone version of the GEC as it looks really special, the Antique Green is good though.
The GEC is the more unusual knife, another closer test would be a CASE v GEC 66 Serp same blades, again different animals.
Hope this is some use, Will
