I'm no expert, but here's my take, for what it's worth:
The "white crap" in that other pipe may be mold. Did you do the salt treatment? The interior walls don't appear to be pitted and cracked like the other pipe, so salt and alcohol should be fine. For pitted and cracked bowls like the pipe in your first picture here, you may want to use cotton balls instead -- pack the bowl with cotton balls and pour some high proof alcohol over them (just enough to dampen the balls), then let it sit, bowl rim pointing up, at least over night.
The first pipe pictured here appears, to me, to need a good reaming. The bowl's walls are thick enough so that a good reaming, to the wood, should remove those cracks and uneven cake nicely. A good pipe reamer is about $20. If you have a decent tobacconist near you and you're fairly charming, he may let you use one for free. Can't hurt to ask.
For all estate pipes: Be sure to clean out the shank thoroughly with a shank brush ($1), alcohol, Q-Tips and pipe cleaners. Dip the shank brush so it holds the alcohol and scrub, followed by Q-Tips, then wash the shank brush with a little dish soap until it comes clean, rinse it, dry it and do it again. Repeat this until the Q-Tips come out clean, then use the pipe cleaners, starting with a bristle one (if you have them - if not a regular pipe cleaner will work) -- until a regular pipe cleaner comes out clean. Again, let it dry thoroughly, at least overnight. You may have to pack salt and alcohol in the shank as well if a ghost persists when you smoke your otherwise cleaned pipe.
