CD 134 AM. INSR CO. BASE Embossed backward N glass dot

Embossed on the (Base) AM.INSR CO [glass dot] PATd SEPT.13.'81 { the N is backward in INSR} This style of insulator was highly prone to damage especially on the upper and lower wire groove rims. Not on this one, it does has a couple of flea bites but NO DAMAGE TO THE EMBOSSING OR WIRE RIMS look at the photos. As a bonus there are white milk stringers thru out the glass. The top of the pin hole is very crude and the threading at this point is non- existent, but the glass button is still present at the top of the pin hole. To be on the safe side I will call it VNM and you can call it yours for only ---$55.00--- Buy with confidence! … We do not sell altered insulators! PayPal, Money Order, or Cashier's Check.
