Here's a Westinghouse lightning arrestor with the crossarm mounting bracket. I'm no expert on these, but to me it looks like an older style. It's in great shape, large Westinghouse logo incused into the top. About 7-3/4" inches high, weighs in at around 7 pounds. $10 + shipping. Ready for mounting (to a crossarm). E-mail with any questions and thanks for looking.
