Thank you, Gerd, for getting us straight on this one.
I am not making excuses either, but I too was misled by what is on the Internet.
I found the car almost immediately on one of my better reference sites and kept tracking it down
I found the same car, same photo on a Czech site, a Russian site, a French site and a Hungarian site
in addition to the original German site I normally use. Every one of them identified it as a Frazer Nash BMW 315/1
and I think one or two of the sites mentioned RHD.
Having now found my copy of Schrader's book, it is obviously one of Weinberger's creations as the photo was
taken in the same Park as dozens of their other works. It is also mentioned on another site I use, but did not check
this time, as a Weinberger creation and that site is usually very accurate also. Like Majeko, I was stuck on Frazer Nash BMW and did not check just BMW.
Good detective work Gerd.
