Need to see inner workings of functioning Remington Mark II. Recently purchased one that isn't working properly. Bell isn't dinging, ribbon isn't advancing &the font will not change into red. Wanting to see pictures of the right side of the typewriter taken out of the cover, while in the black, red, and correction modes. Also, can someone please tell me what the double arrow key is meant for? Any direction to an owner's manual would be great as well. Thank you in advance- Mariah
