In the first pic, the cats with just one piece in the middle are Peltier Bananas.The best bananas are squared off at the end. The green cats near the top look like they may be Jello ones, I know what they look like but forget who makes them. They look kind of jelly like, see thru.
The second pic look like Peltier Patches, which would make sense if they were originally all together. Take a look at this page: The Peltier Glass Company 8
