I say replacing the toe... haha, what I mean is that dark bit in the toe in the first few pictures came off years ago. I glued it back in and sanded it into shape. Thought I did a decent job with it. And yes, hand sanded.
I mainly used the construction adhesive. Ridiculously strong, glued a tile to my house with it and cant pull it off for love nor money now, incredible stuff. I will find out the name of it when I get home tonight if you want. Not sure how its going to go, as I say I will keep you updated!
I have oiled it btw, because it appears this glue is completely unaffected by it! haha
