Given my current preference for smoking only pipes with large chambers, I only buy pipes with that. Have long had the Peterson "Watson" only in the Kinsale version. Love the look of the pipe but it's terribly shallow-more typical of a smaller Rhodesian. Kept looking at the dimensions of the Watson on SP and would have thought it should be a large chambered pipe. Wanted a large chamber Watson, so took the plunge, worried that I'd find it wasn't any deeper than my Kinsale version. Came today and much to my relief it is a large chamber fitting in with my preference. So, seems they may have drilled Kinsales much more shallow when I'd bought mine. My Kinsale Hopkins and Hansom are also rather small chambers and, in the case of the Hopkins, also shallow. Wonder about actual chamber sizes in the SH versions now compared to those.
