Thanks for your response !
I've been giving some serious thought in keeping. Don't know if I would be doing an injustice by slapping some wider tires and turning into a "gravel" bike. There's a really nice gravel trail about 1.5 hours south of me. Or I can just keep her for cruising around the neighborhood and paved trails. Like you said, she is surprisingly lighter than what I would have assumed being an older bike.
Your AD is a looker ! Thank you for sharing
