Offered for sale are an unusual Frank B. Cook telephone lightning arrester and an old porcelain step - down transformer used for vintage door bells. Getting harder to find these as time goes by. Most Cook arresters I see are not marked with his full name so I believe this may be an earlier model.

Asking $40.00 plus postage. Will ship carefully packed and boxed least expensive to your zip code but WILL NOT ship UPS. Sorry, they just break everything.. Will be listing some other stuff this weekend. First yes gets these. Thanks for looking.
