Still working on them

So, the hook thing is looking better after every round of shock/clean.

 

The round thing was starting to shed, too, so I started working on the third, weird piece.

While loosening softened stuff, a chunk off the top broke away -- not good. But, it was interesting anyway: it uncovered the interesting style it and the round one are made in. There are metal strips/strands within.

Haven't done anything with the bolt thing yet. It is not nearly as interesting as the other 3, hehehe. So it will be last.
