First google result that came up when I typed "wirgar lens" was a forum post indicating the manufacturer was Fujita. I believe the Wirgar lens was branded by the Wirgin Bros. who established a rather successful import business in the U.S. during the years the Wirgin factory in Germany was under control of Adox. One of the brothers remained in the U.S. importing cameras and lenses and the other went back to Germany and retook control of the Wirgin factory after WWII.
