Below is a link to an evolving collection of Franz Pott flies,
including various photos of Franz Pott and a photo copy of some
diagrams that accompanied his 1931 patent application, on his
Pott Hair Wing weaving technique. I have a lot of flies (on loan for
a few weeks)
that haven't even been photographed yet. So this collection will be
getting larger in the
weeks to come:
