Things with wings.

Jack could never really be called conservative, he not only ran fore and aft wings they also were set up with anhederal/dihederal!
Shame the 48 valve Repco was so unreliable, the cars were among the best of the lot.

Back in Oz and the Tasman Series Frank Matich tried his version of a March addition on his F5000.

Looks like the Brabham has a hinge in the middle of the rear wing, to compensate for suspension movement?

This failed Lotus 76 has a double rearwing setup. These days it's doing well in Historic racing:

I think (haven't had time to dig through my library!) the dihederal wing was pivoted as an attempt to 1) work with the suspension and 2) to relieve the loading on the wing over 'humps'.
Both the Lotus 49s had enormous accidents at Barcelona in 1969 when the wings collapsed (Chapman just kept on extending them!) and Rindt and Hill were extremely lucky to escape serious injury.
A couple of weeks later after first practice at Monaco the FIA banned them.
Somewhere I have a photo of an F2 Brabham running a very odd 'Triplane' wing, it resembles a box kite mounted on struts.......
I hated that Lotus 76, another one of 'Chunky's' spectacular failures, Ronnie Peterson couldn't get it to work and managed to transform his car into the Lotus 72E!

the stock cars ,XX-Ronny Youngman,34-Bill Goss at The Ernie Purcell Memorial speedway (my home track)

these others are at West Capitol speedway ,West Sacramento cal,one of the best if not the best dirt track in the west coast in the 50s to 70s.

And here we have a typically stupid 'Monaco Wing' from the devious and sneaky Tom Walkinshaw. (Arrows).
Failed scrutineering of course.

IIRC The wing was found legal at first, but then the FIA decided it was dangerous for the driver in case it got loose and banned it for that reason.

You're probably right Ferry, I was 'translating' my thoughts from Giorgio Piola's 'analisi technica' yearbooks which were in Italian back then!
I stopped buying F1 related yearbooks in 2003, including Giorgio's erudite little soft covers, in fact I gave up on my Le Mans collection as well.
Must have been a severe case of long lasting cynicism that did it!
