Thanks guys!
As requested...a view from the top of the Zulu. Taken with my iphone...so not the best pic.

A bit more info on all of them.
The GBD is (I think) pre-Comoy as it has a brass logo inlay on the stem. It was unsmoked (until tonight) and only needed minor cleanup of slight oxidation on the stem.
The Sasieni is an estate that appears to have been made between 1946-1950. It is in great shape, but has been slightly over-buffed by whoever restored it. It is a real nice smoker though!
The Kaywoodie Colt is a cute little estate pipe that was either very lightly used, or very well restored. I believe the Colt designates that it was a smaller than standard pipe (it measures only 4.75" in length).
@ Collin: This may explain why it doesn't seem as curvy. While trying to date this one, I also noticed that mine was more "flat" that any pictures I could find. As for shape numbers...it doesn't have any that I can see. Most of the nomenclature on the shank is pretty clear, so I'm not sure if it was ever stamped with a shape number.
The Kaywoodie Relief Grain was a pipe that came with a lot of unsmoked pipes that had been in a display frame in a pipe shop that closed down. Most of the pipes have severe oxidation on the stems, and it took significant effort to bring this one from orange/yellow to black again.
I have trimmed the stinger off of both the Kaywoodies, as I don't intend to resell them and I like being able to stuff a pipe cleaner all the way through.
