Turbinac

I sent my almost new Kolibri turbine back to Martin Lambert in Germany last September for checking after it didn't spool up as it should. After I chased him to get it back, he sent an email quoting delay as he was moving his workshop. I know how tricky that can be, so I allowed some more time. However, now I can't get any reply when I email him.
Does anyone have any news on Kolibri? Is Martin still in business.
His turbines are little gems, so it'll be a shame if he's gone under.
