I own six R18,19 & 21 cars of their previous 'Wegmann' runs.
ALL of them had severe underframe and brake system problems, wrong heralds and or dates, etc.
So during all those years nothing -except the price- has changed so it seems...;-((
Dismantled the underframes and brake systems, mounted new improved parts.
Took the decals and paint off (they were kind of mud-ish orange) and repainted/redecaled.
Still have to refurbish 4 of them..., just like the prototypes.
