So...can't help but notice the texture is broken because you put the files inside /materials/ instead of /materials/models/. So I fixed that, and did a quick test.
My bad, still new to doing materials/props for TF2, I kind of lazily copied the vmt settings from some other model I dont really remember.
As for the weird phong reflections on the model, I believe its due to how most game engines work, by triangulating the mesh.
The bottom of the pot is getting triangulated, causing it to "split" up each segment into triangles that all converge into the middle point, though technically it all should be flat and not be visible, so I dont know why its reflecting like that, along with odd reflections on the sides (Weird normals maybe?)
I will try to push an update in a moment to address the some of the issues mentioned (file structure and removing phongmask reference)
I actually was trying to make one, but couldn't figure out how to do it quite right, and forgot to remove the vmt references for it before I uploaded.
