Here's a rare Spanish composition No-Tie insulator with an unusual 5/8" pinhole! To date, this is the first and only one I've seen. Previously I've only seen the British style 1/4" pinhole. This may provide evidence of Spanish manufacturing. This unit was used along a railroad line in Spain.

Insulator has wire groove rub and wear marks in the slot, a very small base nibble but no cracks or chips!

First email gets this rare insulator for only $150 plus 11 shipping. Thanks!
