I have for the mud collectors a couple porcelain pieces, one is a Cobalt insulator in Mint condition and the other is a very unique spool in a robin's egg blue with blacky/gray mottling right in the glaze. Their are two indents on top where an embossing would have been but i can't see anything. On the bottom in small print it says Made in Canada, and across from that, two letters that look like "IP" but can't be sure. I've never seen another like this spool, again very unique and its also Mint. Both for $28.00 + shipping.
