This Peterson was a lucky grab. The seller had it listed as a B5 (bulldog) and said it was unsmoked. I thought that it was an XL90 and saw it has Sterling band with a hallmark date. The buyer accepted my offer and the pipe was delivered today. It was indeed an XL90 and unsmoked. The S hallmark shows it was made in 1983. I removed the light oxiation from the stem and she's ready to roll. I have Supreme XL90 that I use, so this one will probably be stored for the time being.
