Repair of Microcord I - 1 - the broken shutter

I recently acquired an MPP Microcord I Mk.1 for repair. The Epsilon shutter had suffered serious damage:-

 

[a] The Arming Lever/Cam assembly on its mounting had been torn out of the baseplate, taking fragments of the baseplate material with it.

 

[b] The interlock tab on the Release Cam was bent down to horizontal, and had a crack on the inside of what had been the bend.
