Collectibles--General (Modern)/Gayner insulator

Question
I have just acquired what I think is an "open screw" Gayner insulator marked No. 48-400 and under that, a small number 7.  I have several Gayners and Lynchburgs but have never seen one that is open at the top with screw threads inside.  Is this a rare piece?  What was its use?  Thank you for your time.

Answer
Thanks for your question -- The Gayner insulators marked 48-400 are a telephone style with threads but not a through hole.  Look carefully at your insulator to make sure the top is not cleanly broken out, sometimes it appears to be a through threaded piece, but the top really has been popped off due to freezing, and it can be pretty clean.  Please attach a picture of your insulator so I can confirm.
