You got a really good deal on that! Condition of your bike is pretty good. I would not advise parting it in any fashion. Good original paint, has some rust here or there, but really just a good thorough cleaning and maybe some new white wall tires, grease her up, and you will really have something nice! Maybe a waxing too. If you desire it to shine up more, like say the chrome of the handle bars, I would advise looking into some methods of polishing up the chrome carefully. There are some good postings on this site with regards to polishing chrome and paint. The bike will always have some weathering and patina to the paint and metal, but that is what gives a vintage bike character. Some people would probably pay around $500 for a vehicle like that if you got it in good working order.
I wish I could find complete bikes like this & in as good conditions for $100 Damn Good deal imo. I'd look into an oxalic acid bath & grease it with some new repro white or gum walls & ride it with pride
