Here is another Canon Canonet QL19 I bought from eBay for my restoration project.
Problem: The meter is not working. The shutter is not working at slow speeds and self timer is not working.
The meter's indicator was unhooked. I took out the galvanometer and cleaned and adjusted the hair spring and the meter came back to life.
The shutter just needed good cleaning.
The camera has been restored and now in good working condition.
