Dear all,

Thanks a lot for all support!

The important detail on this picture is for us the bass string of the 11th course which seems to be a string which is overspun with silver wire. 
Important other details for the datation are given by Jiri Arnet:

But the most important question is the date of the portrait. The date is not 1711 as written in some articles and as file name, but 1716. I found this on p. 25-28 of:
http://www.mdz-nbn-resolving.de/urn/resolver.pl?urn=urn:nbn:de:bvb:12-bsb10915517-1

Johann C. Füssli: Leben Georg Philipp Rugendas und Johann Kupezki, Zürich 1758

So it's one year after the Frauenzimmer-Lexikon, in which the first time the use of overspun strings on a lute instrument is mentioned - as far as I know. (The Piccinini citation is very unclear and it's not very probable that he meant overspun strings.)

All the best

Andreas
