I have e-mailed him a few times regarding Ikoflexes, but I have never actually sent anything to him. I have read other posts regarding his work on Rolleis, people seem to be satisfied. I wouldn't hesitate to send anything to him. I just checked out his website, he's in the process of moving so communication with him may be slow. Normally, I think his turnaround time is 4-6 weeks on a job.
There is no major issue with it at this point, but it's old, with intermittent overexposure (shutter service), and some wonky frame spacing also intermittently. So it's more about giving it a full service before it gets worse.
