On the right is a CD 1104 embossed B on the front and No3 on the reverse. Normal nibbling on the top end of the hole, otherwise in very good shape. On the left I think I have a CD 1106. I measure it 2" x 2". There is a shallow, one half finger nail size chip at each end of the insulator. Asking just $25.00 for the pair, plus actual shipping cost to your US address. PayPal, friend mode, or check.
