I am in the process of restoring this bike for my uncle as a Valentine's surprise for his wife. The serial number is D444665 so I know the year is 1964, but not sure on the model. I just realized that the upper bar has some tabs on the bottom of it which I am guessing is for a slimline tank. Can I look for anything else that can help me find the model so I can make sure I repaint it the original color, which I think is blue. Below is a crappy screen shot of a video I made. Any help is greatly appreciated.
