Hello, I have the following Tek Instruction Manuals sitting here. I would like to free up the space they are consuming. If someone wants to make it worth my while to spend the time shipping them out, I will entertain offers. Otherwise, I will dump them in the recycling. Preference will go to the fewest number of boxes I have to deal with and, of course, compensation offered. I will accept offers until Sunday (28th) evening. I will ship or recycle Monday. Shipping from 53714.
