I'm trying to rebuild my Ceriani forks so I can sell them

I cant find any online manuals for them anywhere or any parts either. does anyone know of a manual or parts diagram for them online anywhere?
also i cant figure out if the bottom of the damper assembly comes off or not. (the part that seats into the fork leg)
the Ceriani damper tube is aluminum which I think is odd, I've never seen that before. usually it is steel and the bottom part is aluminum.
if you heat up the bottom part a bit it will generally fall right off. The Ceriani's seem to be pressed on I'm not sure they will come off.
Does anyone have any of these parts as spares?
Thanks, Aaron
