hello Larry - welcome to the GMB

regret I'm ignorant of your two pieces, but hopefully someone will have an idea - you may have to wait a day or so as not everyone looks in on a regular basis, but in the meantime, and just to give you an idea of the formalities and habits of the GMB, would suggest the following.
To avoid possible confusion during discussions, experience shows that it's better to restrict each post to a single item of glass - and posting from your own library to the Board directly is better than an external host - apparently it provides a longer life to your images - they don't disappear without warning. Are you able to send pix from your camera to your pc, then re-size and upload to the GMB? Pix will need resizing with the larger dimension at 700 - there are technical tips here under the advice section if your experience problems, and shout if you still have problems.
Your descriptions of the bases will be improved if we can see a suitable picture - the 'underneath' of glass can say so much.
Have to say that 'unpolished' bases do worry me a tad - Italian glass has a good reputation, usually, and is mostly well finished, though pieces from other parts of the globe are of lesser quality often.
Hope this doesn't daunt and look forward to seeing further images. Not that it will help with an id, but sometimes interesting to know the source of items.
