I have a large assortment of Risograph GR parts...clutch, front and side covers, circuit boards, exit feed tray, used master box, papeer feed with rubber rollers, impression rubber roller and much more. All in working condition and very little use. I am closing my shop and need to sell now at some price. I also have blue, red, green GR inks. Call me at 352-206-2679 for your special low price or e-mail me at printking01@yahoo.com. thank you....John
