Here is a nice pair of porcelain insulators from New Zealand. The spool is large (5"x5") and has a lot of character as it is quite different than domestic spools I've dealt with. It is marked G/N.Z.I./ 59.

The unipart cabletop is marked B/N.Z.I./58 and has the pin cemented inside. Both pieces show no damage and few signs of use.

I am asking $30 for the spool and $15 for the cabletop, plus shipping. Buy both for $40 plus shipping.
