CD 102 Insulator help

[bottlerocket]

I found an insulator today that is not typical to what I have been finding. It is smaller and from what I reasearched, is a CD 102.There are no manufacturer markings such as Brookfield or Hemminger. There is no star or diamond shape.Just 3 dates on the top dome area of the insulator.PAT JAN 25TH 1870FEB 22ND 1870MCH 20TH 1877I guess you can call it aqua colored.The question I had is who made this, how old is this, what type of communication OR power did it serve to insulate, is it considered collectable?I have quite a few Insulators PAT 1893 that have Petticoat HG CO and some Postal insulators but this one is the only one I have found in the same area as the others that has an older PAT and quite a bit smaller.Any information is appreciated.

Don't quote me on this, but I believe this was made by Brookfield (early days?) It's considered/listed in the price guide as CD 102 "Patent-Other" and has a book value of $5-$10. Looks like there is some amber swirling mixed in the glass? Someone else who knows more will cone along and help.

Thanks sparrow. There is some kind of swirl in the glass.

Would have been a telephone insulator. Pretty good, strong embossing for one of those. A good number of them had weak embossing. Nice find.

You are gathering all the correct information and Chris is correct about it being a BROOKFIELD and approximate value. It was used for Telegraph communication and later Telephone, and perhaps light power applications by individuals. The dates of use are late 1870s up through early 1900s. The industry and hobby call this style "PONY""PONIES". Odd because I've never heard any other style referred to as any sort of horse.Hope this helps a little.

The story I've heard is Western Union coined the term 'Pony' for this style because it was a smaller version of their standard insulator, the CD 126 blob top. This must have been in the late 1870's or 1880's. I guess the name just stuck after that. Weird that the CD 120 is the only style that actually ever had the word Pony embossed on the insulator.

I have some information on glass insulators,. but not enough I guess because I have a green BROOKFIELD where the top was tooled as an open reverse hole about that is about an inch and a quarter that tapers in to a 3/4" hole. It doesn't make much sense because rain water would deteriorate the threaded wooden pin.Not my main interest - it just got res erected from a storage box. RED M.
