Epsilon shutter in Ensign Selfix 1620

[Stuart Walker]

Has anyone experience of getting inside the above shutter? I've removed teh shutter from the camera, removed front and back lens elements, but there is no ring evident in the front to get further in. There is a black cover ring with the infinity stop in it, which I assume has to be removed. However it is not obvious how it comes off. Does the infinity stop hold the ring on, and if it does how is the stop fixed on?

Keith South of The Living Image Camera Museum licm.org.uk/ kindly sent me some instructions and photos. The second element unscrews out with its holder, but was quite tight. I was able to grip it in a three jaw lathe chuck. There is another ring with slots underneath that which releases the front plate.
