Three spools from three different materials. Left is a blue-gray porcelain Lapp with no damage. Middle is a NN with that brick like stuff. Don't remember what it's called. Bake-o-lite or somethin'. I'm sure Prof. Rick will chime in with the answer. Some large "chips" on side opposite picture. Right is a clear Hemingray-518 with no liner. Has typical chiplets along rim otherwise VNM. Take all three for $12.00 + shipping. First email that says' "I'll take it.". No PayPal. Email with questions.
