Antique Vtg 1920’s Folding Corona No. 3 Portable Typewriter & Case

This is such a cool typewriter with a carriage that folds over the keys while in its storage / carry case. This kind of works, but needs someone to help it out. The ribbon isn’t advancing and the ribbon isn’t on any kind of reel, so I’m guessing that’s why. It looks like the mechanism and parts that would make it move are working properly, there’s just nothing to catch and advance with no reel. Also the carriage only advances after each letter if I manually move the part that adds the space. It will occasionally move without being manually manipulated so I think it might just need some oiling. I can see where it works and it’s not broken, just sticky. A few of the keys are a little sticky as well, and again probably just need oiled. The case has obvious surface wear, but is pretty solid and the latch works well. Weighs approx 8.5 lbs in case. Outer dimensions of case are approx 11.5” x 10” x 4.5”. Let me know if you have any questions.
