Thanks.
The meerschaum stem is only a bit overclocked. I think I can rehab it sufficiently for government work with just a bit of a shim. maybe a bit of light polish on the end of the stem to lighten the scuff marks, and it should be fine.
The cob is a throwaway, as it is a $4 item. I may play with it, just to kill time, but have no real illusions about saving it for posterity.
The far right upper is possibly a goner, as well. The hole for the stem is wallowed out pretty well. I imagine it can be repaired, but I don't think the pipe is worth the repair. In any case, when I get some fundage specifically for this sort of thing, I will take them to a pipe shop and inquire about possible repair strategies. As it stands, I have an extra pipe now with a minor shim job due, and that is more than I started with this morning.
