The striped beads have nothing to do with chevron beads, as there is not a trace of star molding in sight. I could be wrong, but they look an awful lot like beads that are currently coming out of Indonesia. They come in plain colours and striped, and they were for sale at Tucson for 2 dollars a strand. I bought, among other colours, these blue striped ones. They are interesting to use in jewelry because of their irregularity, but they are not old at all. The stripes are probably made in the same way stripes are made on for example seed beads; by adding several strips to the outside of the piece of glass before pulling it into a long tube that can be made into seed beads.

Don't know enough about the other beads to ID them. They look like some of the nila beads I have. However, presuming I am right about the striped beads, I would be hesitant to buy from this seller unless I was very sure of what I was buying myself..
