Blechblas-Instrumentenbau Egger

This is the site of a Swiss manufacturer of brass instruments.  While the bio doesn't specifically mention this, they seem to have a large amount of historic replicas currently in production.  I suppose that a manufacturer wouldn't bother to make instruments like this if there weren't some demand for them, so I think we can take that as an indication that the study and performance of early brass music is alive and well.
