Texas Instruments Nuclear-Chicago R 1000 Strip Chart Recorder, Used Vintage

Description

Texas Instruments Nuclear-Chicago R1000 Rectilinear Strip Chart Recorder, Used, Vintage. Condition is "For parts or not working". Shipped with UPS Ground, or USPS Parcel Select.
Very well built and engineered strip chart recorder from Texas Instruments....From back when T.I. actually made instruments.
Also really heavy, around 28 pounds.
I got it at a Univ. of Arizona surplus equip. auction,  a lot of 2 instruments that I bid on and won.
It looks like has two inkwells to put ink in it.  It also has a needle "zero" lever inside on the lower plate to center the needle on the paper.
I have no idea if it works, never pluged it-in, so is sold has-is/parts.  If you collect nice vintage electrical/electronic instruments, you would probably like this alot.  Thanks for looking
