Well I get $125 for a shutter CLA, Supermatics are moderately easy to service with the manual, and the lens is a Tessar, two air spaced elements in front of the aperture/shutter blades and a cemented pair rear.
To remove the front element unscrew the trim ring using equal pressure on the ring. It may have thread locker on it and Acetone around the threaded edge will dissolve it.
Download this Flash Supermatic Service manual to service the shutter.
