Risograph Riso GR 3750 High Speed Duplicator.
Hasn't been used in a while.
Comes on fine but has drum stock.
Needs drum taken out and paper film removed.
Otherwise fine.
I have 3 drums and supplies sold separately.
I have an SC7500 rip Adobe Postscript 3 also sold separately.
Will upload better photos once I have taken it out of the rear room, where it was used and kept since new.
Please see photos.
