Singer Featherweight Added to My Collection

I've missed several of these machines at auctions and estate sales but I finally was first to get to this one last Thursday. It was listed as pristine in the sales flyer, and the machine may be (although there are a lot of light scratches), but the cord is not. It worked at the estate sale when the cord was held just so, but when it isn't held up, power is cut off. It looks like mine has been repaired a couple of times and that someone unplugged by pulling on the cord instead of the plug. So now I need to replace the plug.

My neighbor has a featherweight, so I borrowed her cord to see how well my machine works and I compared cords. Looks like mine has had several repairs, hers has just one. When I looked online to find out how to replace the plug, a lot of people say they don't like the button foot control and recommend replacing with a clam shell type pedal. I'm still trying to figure out how to thread the machine, so I haven't spent any time with this pedal yet.

The machine came with a box, a tray that slips onto the side of the box, a spare screw (or it could be a screw from something else that the previous owner just threw in there), a bobbin, and a bobbin case. If anyone knows what the screw is for, please let me know.

Also, if you know what the two holes in the base are for, please let me know that also. My neighbor said she figured they were for oil, but they are threaded so I wonder about that.

Now I'm off to find out how to thread it and how to fit it in the case. The way they had it at the sale, the screw on the face of the machine rubbed a spot in the fold up bed extension.
