stoneware insulaters?

Hi there, cool finds. Usually we refer to them as porcelain, and they are generally, but not always, more modern and more common than the glass ones. That one you have there is a shape a little different than any I have, pretty neat. The glass one looks like a common 'pony' insulator as they call many of the small ones. But even on really common glass insulators be sure to look for milky or amber swirls in the glass as that can turn a fifty cent insulator into a $50 or $100+ piece real quick. Also pretty neat you got the side pin, though it looks kind of beat up people love to use those for displaying their insulators. You can save up 10 or 20 side pins (not the straight ones) and get a few dollars for them on ebay.

Thanks for sharing, I haven't recovered any insulators from the wild for a long time...

i call em mud, not implying that they arent good insulators by saing so but it's easier to say mud than ceramic. I would say 1920's-30's for that one, and around 1905-1910 for the hemingray 12. Not too rare, but good finds of course. keep lookin around that spot.

P.S. I believe the porcelain insulator you have there would have been used for power lines, the cable would have sat in the saddle groove on top. I also think it is called an eared or helmet insulator, for obvious reasons, and they are in general tougher to find than many other porcelain insulators. I believe it is one of the more common helmets, but still a relatively uncommon insulator to find. The small Hemingray you have was probably used for local (in town) telephone lines.

I have found several ceramic insulators along abandoned railroad lines. Many of which are marked with CPR. Back home, in Bermuda, I usually find ceramic insulaters that are dated any wheres from 1899 - 1909 and are stamped with the British Broad arrow mark. I love finding them, i think they are a key addition to the stoneware section of any collection.
