Before you start priming the frame and forks, how about posting photo's of the frame serial number and year stampings. Can you also post a photo of the fork date code stamped on the rear of the fork horizontal plate. All of these stampings should be easy to read without the paint. Also, Johan is correct about the front forks. The only WWII Huffman's, that I am aware of, to use the style you have were the very early 1942 ( Approx., Jan. - Feb.) with the curved lower frame tube.
