I put up a zip that has 2 of the license pages from my old site to help you determine what the original licenses by Az were and so you can decide which items were from this collection. I can't give -or not give - permission regarding these models but maybe these will help you determine what to use, or if you do post you might be able to create a copy of these (removing all my old side text from the site) if you are going to make them available for your own protection.
