Another neat duplex insulator. We'll call it Green Aqua. Couple small dings, typical roughness on the pinhole and an open bubble on the top inside above the threads.
Aqua is $15-20, Green $40-50. To be conservative, we will put this at the aqua end for $17 plus shipping. Buy this and the [id=182020883; CD 187] for $25 plus shipping.
