A network for historic guitars and vihuelas
I'd be grateful for any information about this person and works, other than that which appears in Bone (1954 edition).
The Rischel collection also contains a number of his works; in particular a couple of trios Op. 8 and Op.9
searching in the Rischel collecion his namre appears. It is Carl as You suggested. But unfortunatly I know nothing of his life. I do know these trios You mention.
