Here are five different radio strains in clear, straw, and delft blue. The Pyrex is the only one marked, and the delft blue is the only one mint. It measures 3 ¾". The rest are 3 5/8", 3 7/8", 4 ½", and 7". The Pyrex and the one next to it have fractures at one and both eyes, respectively, and the other two have minor tics and flakes. The eyes on the middle piece seem to be larger than usual. Asking $30 plus postage for the group.
