[meteorite-list] Question specialist

[Aleksandr V. Leonenko]

Greetings to all!
In advance I am sorry for my bad English.
For a long time I am engaged in searches of meteorites in the Central 
Asia. But stones represented on a photo cause in me difficulties in 
definition. I understand that on a photo to judge difficult, but I will 
be grateful to all who will answer.
Whether it is necessary to do the spectral analysis?
They are similar to what kinds of meteorites? (If are similar)
