Identification of Pocket Watch Movement

[Magical]

I should be grateful for assistance in identifying the pocket watch that I am currently working on, together on any advice on where I may be able to obtain a clickspring from.

Looks very much like a Parrenin X40.

HSL, Many thanks for your quick response. As the clickspring is missing my next challenge is to source or fabricate a clickspring. I'm not quite sure what general shape/type the clickspring should be.

On a click like that you probably would have an ordinary round click spring.
Not to hard to make a new one.

One can use material like this, you just have to make the two small end angles so it fitts.

Hi      Hsl is spot on  Here are another couple of pictures front and back from Ranfft.

Further disassembly revealed that the click spring is a Shepherds Hook shape, which is housed under the ratchet wheel. I managed to fashion a new spring out of a small piece of guitar string. Thanks to HSL and watchweasol for their advice, much appreciated.
