Here's a very rare Green Blackglass CD 106 embossed SM-1 in VNM++ condition with no chips or cracks and only very light dome scratches. Price guide lists this as "No Name Mexico", but it was recovered in Brazil. I am only aware of one other example.

First email gets this rare and desirable insulator for only $1250 (low book value) and I'll include free shipping/insurance. Will accept payment divided up to 6 months. Thanks!
