Here is a tough to find CD in good shape as these go:

CD 243 HEMINGRAY-88 // MADE IN U.S.A. -- SDP -- hemingray blue -- three base chips affecting 10 drips (see pics) -- not many of these early and large power pieces around -- $1850 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.
