Here is an Old Shield model created by Tippy. His permissions allow anyone to use this as long as it is not sold and he is credited.

So here it is, up for grabs. I converted it into Blender format.

It is a little under 6,700 verts.

It has no textures but the UV maps are fairly decent.

I like wooden shields. They remind me of the Dark Ages. Good job in creating the model and textures.
