Picked up this Monofil 26 as a project to restore for my collection, yes it is a mess but I just liked the colour. All the chrome parts needed replacing including the click button which I had never done before (hoping I wouldn't crack the plate whilst peening) but it worked out okay! Also I wanted to remove the green knob to install on a new handle (first time again)

This was the mess when it came apart

The salvageable parts cleaned. The click button still needs replacing, and the knob removing from the handle arm, which is in the freezer as I have been told that if you freeze it for 24hrs it helps with removal!
I like those old green 26's too. Please post the results of removing the green knob.
