No I can't prove it. I have seen pictures of Petermax Müller's Pertrix cars (named for a sponsor). They had all-enveloping bodies with had sweeping wings. The central section looks very similar and I thought it might be one with the wings removed and cycle wings fitted to make it a 'intertyp' usable as a sports car or as an open whheeler with the wings removed.
I also owe Petermax Müller's memory an apology - the car was not an eigenbau as he built at least six cars.
Having got that out of the way, could this be Gottfried Vollmer's VW-based special
