Hi Gerry:
Good to see you on this forum ! It's been a long time :)

Can't help you with Gisborne's family tree, but Gisbourne porcelain beehives have several U numbers actually.
U1137 / U1130A / U1135 / U1131 .... depending on which one of his embossings or styles you're looking at.

Hope this helps some.
Robin

Gerry is talking about the unusual insulator mentioned here:
http://cjow.com/archive/article.php?mon ... &year=1977

and here:
http://cjow.com/archive/article.php?mon ... &year=1991

This one with the top missing is the only one that I've heard of outside of the CJOW articles :

I am certain this insulator is the one Gisborne refers to on page 26 of "Inception of Electrical Science and the Evolution of Telegraphy":
http://www.archive.org/details/cihm_03446

Referring to the large insulator upon the table, he said it was very much upon the same principle as the smaller ones in general use, but it took a large pin, and before the pole was put up this pin was strapped to the pole by wire. The pole having been raised, the man with the wire on his shoulder mounted it, and readily tilted it over into the slot where it was secure until it was drawn tight from below, when he could put the tie wire through the hole which ran parallel with the slot, without risk or exertion.

Thanks Robin and Lee for the info on this rare and unusual insulator! I knew only of the one example owned by L.B Elder until i saw the pictures that Craig Boem posted. Now if we could find a picture of that giant pin! :D

Hi Guys:
Oops, sorry about that. :oops:
