Riso ez230 drum nº part. Reference

[JCABRERA]

Hello.

I would like to know the number of the part (Reference) for RISO EZ230 (B4) DRUM. I see S-4886 and S-4889 in some places.
I think S-4886 is the real one (Z-Type Color Drum Compatibility | stencil.wiki) but I'm not sure...

That's all

Thanks!!
