Wade & Butcher identification help please. My first W & B's.

I have my first collection of Wade & Butcher and I think I have their identities but would love help with two of them that look to be regrinds or unspecified.

The first two I believe I have figured out. From top to bottom the first is a FBU that I want to have reconditioned or reground or the best suggestion to correct it.

The second from top is a Medium Size Holow Ground 5/8, and I am not sure the scales are original since I have not seen this style on one before. I would like to keep it as original as possible but I am not sure what it might take to make it safe and shave ready.

Now the next two I need the help with, I would like to identify them properly and then clean and restore as original as possible and I think they would be candidates to keep the original patina and still be usable.

The first is...

Thanks so much for helping a noobie that's trying to get a good collection of W & B's.
