Sinar Auto Shutter, service manual or howto?

Hi,

I have just got myself my first LF kamera. A Sinar F with an "behind the lens" auto shutter.

The shutter seems to operate more or less random so I'm looking for a service manual or an online guide to disassembling the shutter. My online searches has so far only led to the user manual of the camera and not any service manuals.

I'm of course also considering sending it for a CLA but I want to check out the service manual before deciding.

Thanks in advance,

/ Björn

Nice to see another LF-er in town! Have you checked with Sinar if they can help you? Swedish distributor is Molanders - I haven't asked them about Sinars but in general I've found them pretty helpful...
