The following is my email correspondence with Dr. Paul Warren of UCLA regarding my 2000 Dec 16 "meteor-wrong FIND(?)":

Subject: Not all fusion-crusted finds are meteorites

Dear Paul,
When we last met, you made the comment that these recent "questionable finds" that I've been bringing to you would be easier to identify as being meteoritic, if I were "to find them with a fusion crust". Well, I made a find this weekend, and it has a "fusion crust", but this "stone" is very, VERY unlikely to be a meteorite. Whatever this "stone" turns out to be, it clearly exhibits evidence of having experienced an incendiary phase while falling through the atmosphere, yet it is probably man-made, since it looks like no form of asteroidal debris that I have ever seen.
I would be interested in your opinion, particularly before this specimen is cut, because in its current state it represents, to me, the finest example of a meteor-wrong mimicking a meteorite.

Until I bring this specimen down to UCLA, Have a Happy Holiday!

Bob V.

P.S. - Here are some images of my "meteor-wrong FIND(?)".
This one shows its general ORIENTED shape:

This one shows the FUSION CRUST:

This one shows FLOW-LIPPING of the "fusion crust" as it accumulates on the back side of the "oriented" mass:

The "fusion crust" exhibits CONTRACTION CRACKS:

The back side of the "oriented" mass is not crusted over and exhibits small, spheroidal pseudo-CHONDRULES:

Yes, this is very true.  In fact, I have some excellent examples of desert varnish in my meteor-wrong collection.

No magnetic attraction can be discerned.

Nearly half that of non-porous terrestrial granitic rock. (My main counter-indication.)

Please excuse my terminology.  There must be a better term for what I'm trying to describe, 
because I've seen these "cracks" exhibited in many different meteorites. 
(But come to think of it, I can only remember seeing it in small chondritic stones.)

Here's one of my first introductions to this phenomenon of "contraction cracks"
- Lucerne Valley 014 (L5):

NOTE:  The last time that I thought I had found a piece of partially burnt model rocket propellant, 
but turned out to be a chondrite, was the LL6 known as
Lucerne Valley 015 ;-)
