Here's a seldom seen 134.4 in aqua. This one has a sharp raised nipple on the inside at the top of the threads. Damage report: Shallow 1/2" chip on the base that is 1/8" deep. Also, minor flaking at base of threads. Otherwise this piece is in good shape but could use a good cleaning. Asking $120 and that includes shipping. Thanks!

This insulator is no longer available because my listing description is incorrect. Don Briel has informed me it's a 134, not a 134.4. My apologies and thanks, Don!
