Nottingham Interspace JR info

I have an Interspace JR that I am selling. I have the original box and packing material but no instruction manual.
Does anyone have one or know how I an get one? I am trying to figure out how to properly package it for shipping and not sure how to disassemble.

Tried to contact the distributor...ALS group but I don't think they are in business any more.

Thanks.
