Kralik, Poschinger, or Other

I am posting these two vases to get some feedback and opinions. Inspired by Marin's recent post about the Kralik Silver Stripe Twisted vase, I started running around my cases with the black light. To my surprise I discovered that these two vases which I previously thought were both Kralik are actually quite different. The smaller one is UV reactive and the larger one is not. So, on closer examination I discovered that they are actually constructed differently. The small one is an opalescent inner layer with a yellow layer over it and then an extremely thin layer of opalescent over that. The larger one is yellow interior and outer layer with a clear layer in-between. In person they both look alike except for the slight variation of colored spots. So, any guesses which might be Kralik, which is Poschinger or could another company be involved also? I don't think my pictures show the layers very well, but the second picture is the small and the third is the large.
