Metal coil sleeves were used back in the 50's. I'd say the coil sleeve you have found was changed over at some stage !
Just replace with a plastic !
Not quite true Nino - Stern used aluminum coil sleeves in drop target reset coils, I believe right up to their demise in 1984.

Ian - I was referring to the fact that the coil sleeves go all the way back to the 50's. I have plenty of NOS Bally coils with aluminium sleeves.
I agree with the Stern Drop Target coil. I ordered some from PBR some time ago. Not sure if Williams had the sleeves from factory.
