The only book I am aware of that is specifically about buying a Skymaster is from Scott Smith of SkySmith, Inc. I went and pulled the text description from his site:
"How to buy a used Skymaster" book - This book was complied and written by Scott “Sky” Smith. The book includes all of the Skymaster specifications as taken from the Cessna Skymaster type certificates. It includes three view drawings, pictures and performance specifications representative of each of the different models of the Cessna Skymaster produced. There are addition sections about Airworthiness Directives, STC’s and more. All this information for $40.00 plus $5.00 shipping and handling.
To purchase, you can email Scott at
sales@skysmith.com.
For my two cents (we all have them here), I think your plan sounds like a good one. Enjoy!
