Schneider Componon 80mm f4 has a slight rattle?

[Deano]

I have just purchased one of these lenses and it has a slight rattle. Has anybody else on here got one and is this normal?

Just checked mine and it does rattle very slightly, have to hold it near my ear to hear it.
I think it is probably the aperture blades though.
My 50mm is even louder !!!
So Normal ?

I doubt it will be subject to much movement on the enlarger other than up and down slowly for focussing. I would be more concerned about whether it's sharp or not!
