It would depend on what other pipes you intend to put in the case. Barling's, Charatan's, Upshall's etc, no problem. Ferndown's OK too. Peterson's would be debatable. Savinelli's would be a no no and Vaun's would be an act of treason.
Apart from that, I wouldn't give a stuff what pipes go in a bag as long as there is some good tobacco in it too.
