Oh that sucks big time. At least it is repairable. Get a new stem quick. Those Royal Danish Stanwells don't like to be ignored for very long. Hope your day improves. There's a saying something along the line of "eat a live toad the first thing in the morning and nothing worse will happen to you the rest of the day". I think you just had your "live toad".
+1 or is it +2? on Dave at Walker Briar Works. I just got back three pipes of mine he worked on and they look great. Found three more I wasn't sure had made the trip I'm about to pack up to send. He not only does great work, he is very pleasant to deal with and responsive if you have a question.
