Thanks for your comments.
There are definite signs of fusion crust on the back of the right hand object in the first image. Unfortunately it requires a macro image which is beyond the scope of my camera or I would have to cross section a sample.
Incidentally these samples are quite heavy for their sizes.
I'm thinking of testing the samples using X-ray spectroscopy.
I believe a high nickel content is a property for iron meteorites.
Regards
Steven
