RB67 ProS 6x7 120/220 Power Back question

[jdsanika]

Just came across an old style (separate power supply, which I don't have) ProS 6x7 power back. How do you set up the back for 120, the pressure plate currently says 220? Are there different pressure plates? I removed the pressure plate thinking maybe you just reversed the plate but that doesn't work. Thanks in advance.

Do you have a pic or link? You sure its 220 and not Beattie Long Roll?

Memory fading but yes they had two plates with 120 and 220 text, think there was a plastic box to protect the one not in the back.

The back can be used without the power supply using the lever.

Thanks Xmas, that's kind of what I was thinking.
