Well,
I remember very well the vivid discussions about "wind stoppers yes or not" - about 25 -30 years ago when they came up to become popular for the W113 as well. Hardcore fans for and against ....
This invention done by two Daimler-Benz developers; the engineers Hans Götz and Karl-Heinz Baumann carried out their first tests on an R107 in 1986, but only because the other test vehicles of the R129 were already fully booked for other tests. Many little developments and fine steps were necessary until finally the wind deflector was usable for the public - as it is today.
When the R129 finally entered the market in 1989, its 'Windschott' (wind stopper) was already developed and patented ... and also a fully developed and well usable R107 Windschott (wind deflector) was already around ... see above...
So, from there on it was only a very little step by Oris in Markgröningen (near Stuttgart), the manufacturer/supplier of the Windschotts, to adapt the already existing R107 stopper to the Pagoda - and there it was in 1992: A113 860 0074. Only available via the Factory (Daimler-Benz)...
Off note: the upper foldable part of the factory-supplied wind stopper is absolutely identical on the R129, R107 and W113 ....
Since then..., well look around. Almost all modern cabriolets around have a windscreen/wind stopper today.
It is a huge and very positve experience with the wind deflector up - especially with quite "windy" cars like ours.
Longer highway or country road touring even at not-the-best-weather is no uncomfortable endeavour anymore.
I don't remember how often I did late afternoon trips with my freshly restored 230 - all during sunny hours - only to return home while sunset had then already passed. And then it really becomes chilly in the neck.
If you look around on a get-together with a couple of Pagodas - not explicitly car shows perhaps - but let's say 10 or more 113s..., how many have got a windstop today? I would say 8 among 10. That tells you all.
Honestly, although not more the youngest guy, I am still of good health (still) but I do not want to miss the windstop anymore.
You don't need to use it all the time throughout top-down driving but that "meshy" thing really extends the hours where you do not need to put up the top.
Best,
Achim
