I just received a circa 1900 German violin and was immediately struck with the provided case. Evidently a mold was used for both the case body and top. Concrete impregnated cloth layers were placed in the molds and allowed to dry. The exterior was painted black and has the texture of the underlying cloth. Very rigid and inexpensive method of construction. The interior is conventional (for the period) glued on cloth. Without using a scale, it seems slightly heavier than cloth over wood but not at all objectionable. I am quite impressed with it.
The thus protected violin was in wonderful condition.

Well that's pretty cool.
Opportunity is often missed because it wears suspenders and looks like hard work.

I did a google search on the topic and same up with zip. An American architect from the same era used concrete impregnated canvas hung over wires to form thin interior partitions.
If latex paint was substituted for some of the water in the cement mix, the case would be even stronger (and water proof).
