Rokli 6R
A machine of mystery! Clumsily repaired with the wrong crank handle just put loosely in place, but it works if you take it off and just pull out the stub. The machine is one of the final four-function calculators designed by Robert Kling, before they switched to distributing rebranded Schubert machines. I can find no serial number whatsoever, anywhere out- or inside the machine. If anyone could tell me where it should be located, that would be a great help!
