Since a couple of people have contacted me privately already today regarding Simpert Niggl, I would like to post a few observations, just to be a little more economic with my time.
There seem to have been at least two makers of this name in Füssen in the first half of the 18th C., even on the same street. Since the name, symptomatic of the erratic spelling back then, can variously appear as Niggl, Nigg, Nickel, Nigkl, Niggell etc. it all gets rather confusing. In much of the (outdated) literature, these two Niggl get erroneously lumped together as father and son. The one Niggl, born 1710, died 1785, son in law of Johann Ott had no children, his neighbour had 4 sons, Johann Michael, Thomas, Sebastian and Johann Georg (who we meet later in Vienna), so they are certainly not father and son, what relation to each other they might or might not have been is unknown.
So that you can get a rough idea of what one looks like, I will attempt to post pictures of a violin of mine, from Niggl, son in law of Ott, where I unfortunately can't state an exact date, since the last two numbers on the label have entirely faded away. A rather nice Cello from 1743 can be seen in the Landesmuseum Tirol in Innsbruck.
The reason for the sudden interest in Niggl, is this Ebay listing:
http://www.ebay.at/itm/Very-Old-and-Interesting-Antique-18th-Century-Mittenwald-Violin-Klotz-School-/331202843716?pt=LH_DefaultDomain_0&hash=item4d1d3a5444of a “Mittenwald violin made by Sympert Niggel as labelled or by a co-worker or follower”. Since to my best knowledge, there were Sympertus Niggl in Füssen, but not in Mittenwald, this is plainly nonsense, if not an oxymoron. The violin is most likely from Mittenwald, towards the end of the 18th. C, a couple of generations too late to match the ebay description and will be impossibly difficult to ascribe to a particular individual, since it would seem that much of the village built violins at the time.
NB: the violin has a SOUNDPOST CRACK IN THE BACK, and, from the end pin view, has cracks beneath the chin rest, which will require attention (i.e. belly removal)
