This is a terrific machine! The FR serial number indicates a Family Rotary machine, and mine is my favorite machine out of 14 others. You may consider soaking the (non decal) rusted parts in vinegar overnight, then brushing off with water and a toothbrush, followed with a nice oil bath.
The bobbin case cover appears to be a replacement; they are often missing on FR machines. I eventually just started making them out of 1/16 plexiglas (easy to work with and lots of fun to watch the machine work).
I would Not recommend trying to remove the handwheel; it may be flared at the right end. An article on Treadle On mentioned a gentleman using a gear puller (!) to remove one, only to find out the wheel is not designed to come off the shaft left-to-right.
I love these machines. In spite of already having 15, I want another FR...I would gladly trade a Singer for one in decent condition!
