Yes – transition in 1972, but why? The costs for molds (prototypes!), production, marketing etc. were to high: not enough revenue to get earnings for the new owner – to name a few problems…

“Concentrations” etc. means: LEAN PRODUCTION – less forms, less variations, less experiments with non-Lectron units, like the TRIAX project.

That has nothing to do with the RWO – that was a cost-free support of Mr. and Mrs. Kopperschmidt for nearly 20 years, but with huge inactivity of RWO (…”they had to be carried in a litter to the hunt…”) that’s the truth!
