Nice group of four different CD 251 Hemingray insulators. -- Left is a -61 (030) in clear with the corrugated base. Has two flea bites to top and a matchead flake off of rear ring. Next is a No. 1 Cable (070) with patent date on reverse in aqua. Has a lower front skirt chip that causes one partially chipped SDP and also has an inner skirt flake. Next is a -61 (040) smooth base with no damage. Right is a No. 61 Cable (080) with patent date on reverse in Hemingray blue. Has flea bite to dome, chip to front & rear ring, two lower skirt scallop chips, an inner skirt chip and I count eleven damaged SDPs. Sounds worse than it is as these all display fine ! Low book on these is $55. Take all four of these for $20.00 + shipping. First email that says' "I'll take it.". No PayPal. Email with questions.
