Here is a splendid piece that is a cost effective color option for your collection. The insulator displays mint from the Telegrafos side.
On the rear, there is a thumb-nail sized chip on the upper wire ridge, and a small 1/4" chip close by on the lower wire ridge. As with many of these, there is a thin and narrow glass overpour on the base which has minor chipping.
I am now asking $120 shipped for this insulator to the US. Inquire about the availability of other Mexican insulators available. Friends/Family PayPal preferred.
