Here's a tough U-1954A 2-piece porcelain fuse/cut-out insulator marked Essantee. I got mine over 20 years ago and rarely ever see them offered for sale. These are threaded to use on power poles in Australia and come in a range of really cool color glazes.

These are dry process insulators so the crackly appearance is normal, factory made and not damage. There are 2 small chips on the knife and a tiny glaze nick. These were crudely made and appear to have been hand carved on the base rim. This one comes with the original wire to hold the fuse knife (both included) which are sometimes missing. VNM.

These are very popular and some colorful examples have sold for high amounts at auctions. I'm offering mine for the slashed price of only $50 plus shipping. Thanks!
