Here's a bunch of info I once gathered about the C03/C13/C33
C03/C13/C33 Hunter/Pro-Grip/Pro-Venator
The first C03 was named the 'Hunter' which had a light drop-point blade shape, but actually. it's more of a spear-point with very little belly.
The C13 was a new version of this with more 'belly', krayton inserts and rubber inserts in the clip. The C13 was first named the Pro-Hunter, but that name was already taken by another company, then it was renamed to Pro-Venator, but since nobody could pronounce that properly or knew what it meant, it was renamed again to Pro-Grip in 1999 or so. Funny thing that in the 1999 catalog it is named 'Pro-Grip' but the text refers to 'Pro-Venator'. Before that, the C33 was already called the Pro-Grip.
After the C13 was released, a new version of the C03 was made with the blade of the C13, but with a normal clip and no krayton, but only in CE. Sometimes this one is called the Ironstone Hunter, because it was first marketed by Ironstone (the former Spyderco Factory Outlet), but it has never been an exclusive for Ironstone.
As mentioned earlier, the C33 is the lightweight version of the C13, in FRN with krayton and molded clip. This version has also been marketed as the C13PBK and C13PSBK

Some things I couldn't figure out yet
- what type of clip is on the wood-inlay? ( kinda odd since I had that knife but can't remember it) (Ken you still have it?)
- exact time line of model introduction and steel changes
- all steel variations...
I personally had both the Gary Blanchard types and several variations.
I took some pictures of the Gary Blanchard ones some time ago and they worked out pretty well.
All C03/C13/C33 have been sold but I might just pick up a VG-10 PE if I come across one.
