Though Castello does have a chart of "base-line" shapes, a bit of intentional, individual variation is generally to be expected in the shaping each pipe their artisans create. This particular bent Dublin sports a backward-sweeping flare to the rear edge of the rim, as well as quite a bold heel - not unusual for Castello bent Dublins. Typically, however, those are also accompanied by a conspicuously forward-reaching flare of the front edge of the rim as well. This rendition sports a much subtler touch of that element, which, to my eye at least, only emphasized the just of the heel, as well as producing a sheerer, more solid leading line for the bowl.
