Two early gray glazed 1910-1913 production Austin patent ball socket (OB) strait cap 10" bells with some damage - both for $35 + postage or I can deliver to the western regional for free . (or some other show I am attending ) This insulator is literally the first ball socket connection suspension insulator design ever produced .The gray ones are considerably more unusual then the brown ones . I had two left in the bone pile so they need to find a home . No point to them sitting in my yard when someone else might appreciate them more. Both of these have damage but display nicely.
