Dealership Master Parts Catalog/Binder 1970?

[70cst]

I am startimg to go through my office and garage full of extra parts that I have collected over the years. I want a fair price verses an ebay inflated price so to be fair to those on this site. So the question is...
a) What is a fair asking price for Master Chevrolet Parts Books. 1970
b) Same goes for a Salesman Dealer Communication Box/material. This is a box on information with literature (some have 70 LP records) for teaching the salesman the features and beifits of the new model trucks. I have for years 69 and 70.
c) GM CB's I have three I think Black and wood.

I've had these for a number of years and it doesn't make sense to have multiples and it looks like I will need some extra $$$ for the Circuit Rider as I begin to fine tune her. This is a not FS thread but a thread to get some ideas on pricing. Thanks.
