When I removed the fuel tank in my 1966 C-30, I found a letter written in 1973 by a previous owner wedged between one of the straps and the tank. It looked like a suicide note, because it started with "TO WHO IT MIGHT CONCERN". It went on to say that his wife left him, and rambled on until it was illegible. The guy must have been drunk while writing it. http://www.stovebolt.com/gallery/ducor_doug_1966_01.htm
