This is a CD 303/310 Hemingray Muncie that is the [030] book listing with NO embossing on the back. You may have heard of the song line "I rode through the desert on a horse with no name" well this is a no name Muncie. A great item for the specialty collector since these are very rare compared to the ones with "Muncie Type" . I would say that 1 in 200 are the no name style. The insulator is a nice tealish aqua color and looks to be VNM+++ with no chips or cracks. Asking $175.00 for this unusual piece plus actual shipping cost. I will post a photo of the entire insulator.
