Actually, folks make it harder than it is. Boswell posts new pipes for sale on Thursday. If you see a pipe you like, and it is already sold (sometimes they sell within 10-15 minutes), call the store and tell them which pipe you liked. They usually have 1-2 similar pipes on their wall rack. Boswell posts 10-15 pipes per week on their web page, but has many more in the shop. They can usually get you something similar, but you will have to trust their judgement.
As for the pipes, they are somewhat rustic and larger. They smoke well, but take a little while to break in. Most of the stems are arylic but JM occasionally makes some in vulcanite (I had a vulcanite stemmed Boswell that I enjoyed more than my acrylic). Most of his shapes are freehands, but he does some Rhodesian/Bulldogs with his own flair.
