Ive had this pipe for quite a while....cleaned and never smoked. It has a Dr Grabow stem stuck in it right now.
Figure it could be a good smoker if I had a proper stem
Cheers.
When I need one I order from Peterson of Dublin with a phone call. E-mail them, shop@peterson.ie. It'll be a p-lip they'll be sending you I suspect.
I would suspect that any self-respecting pipe repair would carry replacements also. I'd Google smoking pipe repair and try to locate one close to your location and give them a call.
4Noggins sells the stems, the Medium for a 301, both the fishtail and the P-lip are out of stock, worth a phone call to find out when they might be getting some.
