It was suggested by a Cape-based violin maker some time ago that this unlabelled violin was German and specifically from Mittenwald.
However, there is nothing about this instrument to recommend it as being either German or from Mittenwald. On the contrary, overall workmanship and specifically the varnish would indicate that this violin was probably made in Eastern Europe and more precisely in a Czechoslovakian trade (commercial) studio, some time during the 1960s, or maybe a bit earlier.
The Czechoslovakian output came in different grades, from instruments aimed at complete beginners to violins which were suitable for very advanced playing. Often the latter instruments were really nicely made and well-toned, as is this violin.
This violin follows the Stradivari model and is made of good materials - a fairly attractive mildly-flamed one-piece back of good maple, but with the ribs, neck and scroll being of more plain material. The top is of good quality tone spruce with very fine grain at the centre line opening out to the flanks. Purfling and cornerwork are good and the neck projection is healthy.
The varnish on this violin though tends to be brittle and of quite a hard spirit base - quite characteristic of the Czech workshops. It nevertheless is of an attractive golden-brown colour with a tinge of amber - quite appealing.
This instrument is very well-toned with nice focus and projection and suitable for very advanced playing. It would be suitable as an advanced upgrade which would carry a good student for a very long way, and would also be a viable and worthy alternative to the modern Chinese trade (factory) instruments pandered about as 'handmade' and at grossly exaggerated prices.
(Note: ALL violins are made by hand, or 'handmade', irrespective of the factory they come from. )
