Hi Larry,Greg and list

here are links and photos of all Lunar meteorites that were posted by Ted bunch
a while back
One from?JSC,?and one from Washington University for Lunars, One for Eurites and

one for Basalt textures?from Ted Bunch

I have also a fine grain basalt with a subophitis texture that I will have
tested next year!

May the 1st USA lunar be found, Good luck to all!

Thank you Larry - Sometimes you just can't get your thoughts to the fingertips.
