A great observation about the snail area of Hawken breeches as received! One of the issues is that the nipple sometimes doesn't seat well into its hole in the snail, and there isn't enough room around it to get a wrench. And if you look at pictures of originals, almost all of them have decorative filing that amplifies the grace of the snail. These improvements are easy to do, but the builder must be aware of the need and what was done in the past. Thanks for mentioning it, Troutbum.
