Plain aqua glass insulator only embossed with "CABLE" Hemingray?

This one has no numbers, dots, or manufacturer. I thought it was Hemingray. It is threaded and has its wood post or cap inside. I need help identifying it. Sorry, the pics were upright on my photo viewer. Not sure how to fix them here.
Approximate Measurements:
Height: 4.5"
Width: 3.25"
Weight: 26.6 oz
Voltage: CABLE
Leakage: 4.25 ?
Pin Hole: 1"
Style: Unknown

I think this is Hemingray CD 260 or 259 but it is weighing 26.8 Ounces
Single Petticoat
There are threads below pin hole I believe for a large pin. Width approximately 2.25" but not on the last bottom inch.
The color is a light Ice Aqua. Photographed in different light is making it look clearer than it is.
