Tyrol/Tirol bassics..(Blockless style)

[Jonas Lohse]

I more and more tend to the thesis that most (if not all) blockless basses from the 20th century considered to be from Tirol are actually from Vogtland/Bohemia.
First of all: there are hundreds of known makers from Bohemia. But who can name makers or factories from Tirol?
In the 20th century, the makers weren't able to sell their instruments directly – they 100% depended on the trade companies (aka Fortschicker or Geigenverleger). Most likely, this must have been the powerful companies from the nearby Mittenwald. These trade companies not only bought the instrument from the smaller makers, they also provided the raw and half-finished materials to the makers and decided about the quality and design.
Why should they order a different design from the tirolean makers than from the Mittenwald area makers?
