Rank Taylor Hobson Processor Recorder 5M Model# 112/1604-34 This unit is used and untested by us. It is missing some buttons as seen in pictures. It does power up and display lights up. Buttons ans dials to create a response on the display and the lights associated with the buttons. The screws to keep the top cover on are missing. At some point someone had the unit opened up. I am in the military reserves and will try hard to ship ASAP, but sometimes I am away on duty (which is why I have the 4 day shipping set) Will ship international.
