MM4-60 Focus rattle (1 Viewer)

I love the Fantastic IQ but not so good quality wise re my MM4 60. Despite very little use I had to send it back recently to Opticron due to the fine focus wheel not working - common fault apparently.

On its return I am now hearing a distinct rattle from the internal elements on turning the main or fine focus wheels. Does any one else have this or does it need to go back to Opticron again.

No, my MM4 doesn't do that.
I was hearing a slight squeak in the hot weather on the main wheel but that settled down.
