Every genuine Stroh instrument I’ve examined has had an aluminum horn (or horns) and an aluminum diaphragm. I would question the use of a mica diaphragm or non-aluminum horn. Here are a few photos

Are you saying that Stroviols single string instruments were never made with mica diaphragms back in the very early 1900's and only with aluminium horns?
