In the end, I managed to get 4 different uranium glass canes. The first one was bought at a Prague market. It is opalescent 'annagelb' and can be seen here while being transported on the local bus.

The second and first were classic annagelb and annugrun, both full size rough canes. All three of these are probably from the 1950's. They are one their way to me know by post.

The fourth cane is a smaller piece, and thinner than the others. It shows at the end it was probably used for making molded beads.I think it could be anywhere from 60 to 10 years old. The outside is annagelb, and inside is a green that is not uranium glass.
