I purchased some insulators and in the group were some porcelain that I don't know too much about and would like to know what they are worth. In the picture from left to right.

1. I believe this is a Fred Locke M-3060 tan colored embossed with a bunch of dates, value?

2. I think this one is an M-2140 its unembossed and has a cross top and mahogany brown, value?

3. This is a strain in a brighter green than pic shows, its embossed on top CP 394, 3 1/2" tall, value?

4. This is a dark olive green, don't no the U#, value?

5. Last is a brown spool with a tongue, don't no the U#, value?

Any help on these five would be much appreciated! Thanks.
