Actually 25 pictures looks like too many to post without adding each one to correct place in the text. So I decided to post like that. All pictures are available in full size and original resolution same as original PDF-file.

This little "research" has been initiated by John Dyer, who purchased both samples and shipped to me. Thank you, John, I really enjoyed this little work as it reminded me my past, when researches were main part of my life..
