• Several of the glasshouses that created insulators also produced bottles, fruit jars and other glassware.
• Nineteen insulators, two in white porcelain and marked C.P.R. for Canadian Pacific, plus 1 brown completed insulator with incised MP just about all others blue/green glass by Hemingray.
• The threads of rail screw spikes are produced by hot rolling with specific threading machines.

That’s exactly where these nice deep green insulators come from. So I asked him about them and it turns out all the original insulator collectors were linesmen. They’d go out and do a job and there’d be an old pole with antique insulators on them. They’d swap out the old ones with the new ones and to everyone else, the old were just junk.

Detailed post on the “HEMINGRAY No. 9 / PATENT May well ”pony style insulator employed primarily on telephone lines. There are other web sites that discuss the basic subject of values and prices. One tactic quite a few collectors use is to do keyword searches on ebay or other internet sales internet sites such as etsy.

Intense Yellow Olive Green W

Most came in electric blue, but mine has so significantly milk glass in it, it’s nearly opaque, and I assume it’s 1 of the only ones out there. Nabla rail insulators are made use of in Nabla clip rail fastening systems, working with each other with other fastener components including Nabla clips, screw spikes and spring washers. The wooden insulator “pegs” or “dowels” are additional appropriately named “pins”.
