This specimen was brought to my sister who is working as restaurator of various things and the old lady, who brought it, unfortunately did not know where it is collected.
Gianluigi, Thank you very much. Impressive material! I would be happy to look into your e-library some time :)
I'm checked, but I have only this work. Looking in my e-library? No problem, but you must suggest to me the informatic way. I have over 13.000 titles (73 GB)
