You have a humdinger there. I same that one and it is very nice. I have bee a Jacono (pronounced Yak kamo) for a long time now and Bishop "E's" were my favorite grade. Actually Bishops and Knights were the majority of his production followed by the Queens. It waasn't unitl Smokingpipes.como became the distributor that most every smooth pipe made is now a Rook probably economic reasoning which drives so many decisions in our world.
I hope your Jacono is the sweet pipes it appears to be.
I have a couple Jacono pipes, and they are well engineered. I really like the rustication, but because I'm not a fan of dual feels, I wish they'd not smooth out the rims.
