What makes you think they need a CLA ? In the UK a CLA isn't cheap usually £50 minimum charge
Try the shutters on slow speeds see what they sound like, it's possible to do a small amount of a clean & sometimes shutter work yourself. Shutters can sometimes be cleaned if the glass elements are removed with a bit of acetone or Isopropyl Alcohol without taking then apart. That has resurrected two stick shutters both of which now work perfectly.
I've just tested 6 or 7 Compur/Copal shutters and an Illex using a microphone & Audacity (free wave editor) and all are well within tolerance even the 1920's & 30's shutters.

Thanks Ian.
I have no reason to suspect they need a CLA right now, I just want to be prepared for the eventuality of them not working properly.
However, the spring "thingy" that attaches to the folding front of the camera is there but isn't attached and both cameras appear to have been in a box or drawer for many years. They certainly look like they might benefit from a good scrub and lube.
My DIY skills are not my strongest suit (I am ham-fisted in the extreme), nor do I have the tools, time or inclination to try to fix either (or both) if the test films I put through them show a problem.
As the cameras were a gift from a friend, I don't have a problem spending a few quid on them. Sadly, I'm one of those who gets no enjoyment out of fixing anything mechanical. That they work is the only important issue for me. I have no real interest in the intricacies of how they work.
So, if anyone has details of a good UK-based vintage camera repairer that can handle Voigtlander and Zeiss Ikon, I'd welcome their advices.....
