Czech Glass shapes - copied of inspired?

Here are similar shapes to my last post.
Remember:
- These glass producers existed at the same time
- Had a similar supply of glass products to work with
- Supplied the same customers
- Produced popular items for the season
- Competed with each other
- Collaborated with each other

Who's who:
1. Kralik - Welz - Egg shape lidded dish
2. Kralik - Welz - Lobed trumpet shape
3. Kralik - Welz - (I don't how to describe this shape)
4. Ruckl - Welz - Footed spinning top shape
