Old cot mobile (Whitwick LE67)

I am looking for an old babies cot mobile. I just really need the mechanism to clamp it to the cot so it doesn’t have to be a complete mobile. I am able to make the little figures to dangle. We have very recently become grandparents to beautiful twin girls so not only double trouble but double expense! If anyone has an old one or no longer needed I would be most grateful.
