Here is a cornflower blue 106.1 Duquesne that is the cleanest you'll ever find. Couple of thread cooling lines that are more like pour lines, this one is mint. And the cornflower is deep. Typically, the wire groove areas on these are rough, this one is uncommonly clean however. The "ribs" going from upper skirt to lower ridge are bold, and perfect. You won't come across a better example. Asking 195, plus S&H
