Last Thursday I visited a antique center after driving my wife and child to the doctor. My wife patiently awaited my return in the our car. Finally I returned after around one half our with the Dark Green Brookfield CD 164 on the right in my pic. When home again I compared it to other CD 164's in my collection. To my surprise it was made from the same mold as the yellow green with amber on the left. That fact may have been not detected if not of three very tiny scattered dots located in the same area of the #6 shop number embossed on the top.

I visit the same antique center quite frequently. I think the seller has had a booth for some time but this was a first time he had any insulators. Being he had mis-marked the price on the green 164 the person/friend of mine had to call him on the phone in order to obtain a correction. Turned out he was on the way to the center and we met in person. He and his wife promised they would bring others that the thought might interest me in the near future. I've had promises made by other sellers in the same center with no results. Hopefully I will not be disappointed this time around.
