Missing fork circlip dimensions

[RobinSF1]

Just changed front tyre and fork oil and the slider came off one fork leg without undoing the screw. Upon inspection I found a circlip loose in the bottom of the slider and managed to retrieve it. It appears too big for the stanchion. Does anyone know what dimensions the circlip should be?

Mdina don't list them, whilst I could try getting a few different sizes from Simply Bearings and seeing what fits. It would be good to know what size the circlip should be.
