The insulator in question is the piece on the right in my pic and the one I'm selling on this ad (I will throw other in if buyer wants at no extra charge except to Canada). Don't know how rare these actually are. Don't recall ever having or finding one myself before. As you can see the skirt goes up much higher then your tipical 133 to the left. This one has some milk mostly on the left side that starts in the back and ends up fanning back up from the base. Looks like sun rays high lighting BROOK of Brookfield. Very cool. I can send close up pics of milk if need be and requested. As for condition I only see one flea bite at the top of the dome on this crude littl.e insulator. The rear skirt also has a couple spots where the glass is colapsing inward. Lastly, I think this insulator is slug embossed.

First emailer will have some nice insulator added to their collection for $30.00 east of Mississippi, $32.50 west of Mississippi or $40.00 USA dollars to Canada. Pay Pal non-fee, personal or money order checks accepted as payment.
