Ceriani 35mm fork tubes / stanchions

[pepron]

Hi,

My Ceriani fork tubes are slightly bend, so I ordered new ones.
I?m very confused as the old ones contain a brass tube or sleeve inside the fork tube and the new ones don?t. It Is a press fit in the middle of the tubes and about 20 cm long.
I don?t understand the use, or is it a kind of stop for the damping rod?

Has anyone seen this before?

Regards,
Ron

I bought them by Stein-Dinse a German supplier. The new ones look identical to the old ones.
I couldn?t find anyone in Switzerland to um-bend the old ones. I?m not sure are the old tubes originals from 1973. It looks that the fork has been rebuild before. Internals look very good. Discard my  ?damper rod stop theory? the inside tubes are to far up in the stanchions. They are 160mm from top. Is it a oil level mark or has someone added additional strength to the stanchions by fitting an inner tube?
