Unusual white 2 wire porcelain crossarm $150 postpaid. 21.75" long, 1" thick, 2.25" wide at the narrow end, 12" from one wire slot to another. The December 2018 Bill & Jill auction had one of these in it that sold for $198 plus postage (https://www.billandjillinsulators.com/auctions/151/view/?lot=179). This one is in mint condition. A U-shaped bracket goes around the end and a bolt connects it to the porcelain. A hole in the bottom of the "U" allows a bolt to connect the bracket to something else like a pole or metal structure. A strap, like the straps used as crossarm braces, are used on each side of the center of the piece and secured to the porcelain with a bolt or pin that goes through the porcelain. The straps are then secured at the other end to a structure. PayPal (to com574@clcillinois.edu), check, or money order is fine. Rick Soller. Originally asking $150, now $110 postpaid.
