Collector Gary Michener says this ordinary looking CD 102 pony is his favorite insulator. What's not ordinary about it is the embossing: So. Mass. Tel. Co. Founded in the late 1870's, the Southern Massachusetts Telephone Company served Cape Cod communities until well into the 1900's. Only a handful of examples have been found by collectors. It's the rarity of this little pony that captured Gary's fancy from the time he first saw it.
