The first reader to guess what the image below is, with the manufacturer name and model number, will get first choice of a list of books to follow. The next five readers to do that will get their choice of the remaining books in order of who is second, third, etc.
I am sorry that I cannot ship internationally; I can only ship in the continental US, but I invite anyone outside the US to guess as well because you are also important to me and our audience.
The books are as follows:
The TAB Battery Book: An In-depth guide to construction, design, and use, Michael Root
Solenoid Control, Testing, and Servicing: A Handy reference for engineers and technicians, Robert M. Haney
The Eureka Method: How to think like an inventor, John Hershey
How to diagnose and fix everything electronic, Michael Jay Geir
The power of design: Product innovation in sustainable energy technologies, A. Reinders, J. Carel Diehl, H. Brezet
In my recent travels, I encountered this vintage piece of electrical work that caught my attention. I will let you know where I saw this item and I will give a good detailed description about it once the contest is over.
The contest will last for two weeks and end on Friday, July 28.
Take a good look and give me your best, educated guess with as much detail as possible.
