Not all uranium glass is pressed and uranium glass is still being made, so nothing is too new to be uranium. Your footed bowl I suspect is Czech and something like 1940s/50s, but I've not found a manufacturer yet (it also comes with slightly different engraving).
I don't think any of your vases are Sowerby, even the small one (that looks like Stoezle might be a better candidate). For a start the colour is wrong; Sowerby uranium glass is a yellowish green. The Sowerby 2684 is the bird panel vase discussed here
http://www.glassmessages.com/index.php/topic,2818.0.html and when made by Sowerby wouldn't have been in uranium at that sort of date.
These plain vases are always difficult but if you have time to spare I suggest a root through
http://www.glas-musterbuch.de/ and
http://www.pressglas-pavillon.de/index2.htmlNext time please post one item per thread to keep things simple and I also suggest you use the boards attach facility rather than an external link as it keeps the picture with the thread for future reference.
