Here's a RARE Spanish Narrow Slot-Top porcelain insulator (on the left). Made by Guerin y Comas in Barcelona (which has connections to famous French porcelain manufacturer) in circa 1900-10! Their early catalog shows these were made in 3 sizes (all with narrow slots!) but rarely seen and first offered on ICON. Other manufacturers made them with the wide slots. Measures 3 1/4" wide x 5 1/4" tall. This unlisted beauty is in excellent condition with only a 1/2 pinky nail flake!

The smaller scarce Wide-Slot porcelain on the right is also available. Measures 3" wide x 5" tall. Very crudely made. Several factory nibbles inside slot are glazed over and not considered damage. 3 small flakes in groove (one pinky nail, one 1/2 pinky nail and one match head size). Unmarked. Circa 1900-10.

First email gets the Rare Narrow-Slot for only $250 plus shipping or $150 plus shipping for the Scarce Wide slot. Buy them both for only $350 and FREE shipping. Price is firm. Thanks!
