I digged up already > 70 ever produced desmo-systems.
Twentyseven minus sixteen solved in the mean time makes eleven* systems that are still more or less a mystery to me.
Who can solve the hereunder mentioned mysteries? Pictures; drawings; articles; everything is welcome!
Please take a look at “Systems” also for further information.
Contact me by email: [In Dutch; English; German and French].
