More marbles to identify

[Byerspb]

I hate to keep asking for help with identifying marbles but here we go.  Five more here.  Tried to take good pictures.  The second from left I'm guessing Marble King.  Let's see how I'm doing.  The last on the right has a Z shape design on it. Again I appreciate the help. I've been selecting out the best ones to post.  Got more.

I am still learning but will make a guess at them.

1. Alley

2. Marble King

3. Pelt rainbo

4. ? 

5. Akro corkscrew

You nailed it!  Right down to the question mark! lol

I'm not sure on that one either.  I'm leaning strongly Master for now.  More photos could help.  Maybe an underwater photo to cut down on surface glare and reveal the inside?

Thanks!  Here more pictures of the marble in question. #4. Outside and in a glass of water.  Purple color showed thru.

Because of the colors, I am sticking with Master.  It looks like it could be in the Tiger Eye family.  Not the earliest, purest example, but possibly still Master Marble, before Master turned into Master Glass.

 

That's my hunch.  Not putting any money on the bet, but that's my hunch.

Thank you.  That helps!
