Here is a very nice Brookfield power piece that is seldom seen:

CD 236 BROOKFIELD -- dark aqua -- area of nibbling at the rear ear side & a no glass missing inner skirt bruise -- $675 plus actual postage

NOTE: I'm selling these insulators on behalf of the Jim Fielding estate -- PayPal (no fee friends and family) or checks are both accepted - I'll provide instructions. I'll also be handling all the packing and mailing.
