Dear Edwin,
that´s the attitude of a true Lange fan!!
In fact it´s not as telling view from a distance; on close encounter, i´m relatively confident it will be pretty "catchy".
Well, i´m not sure about engravings; after all, the triangle-shaped part rests on a vital section (the pinion which combines both third wheels), so it has to be equilibrated very well to work properly. Aside, it´s certainly not *that* large 
But i really like your idea of an A3-size rendering.
That´s a very nice suggestion - will see if such can be brought to life.
Cheers,
Peter
