Here are more pictures of the bobbin area. I cleaned the bobbin case but it was a worse color than the bobbin. I see 3 holes in the black bottom of machine I think are for oiling. Tell me if I’m wrong. The silver needle plate has one hole for the needle and one hole right of foot.
It must have had a lot of gold on it at one time because yesterday afternoon the sunlight shining on it you could see faintly where it was a lot on the head and the flat part. I bet it was a beauty when new.
I appreciate you sharing your knowledge about this machine and if you need anything else let me know please. Thank you

:shock: Good eye, Dunster. That sure surprises me. It is a 115. A manual can be found at https://ismacs.net/singer_sewing_mac...ine-manual.pdf and https://www.manualslib.com/manual/79...inger-115.html

What it would look like with the original decals - can be seen at

It is hard to tell the colors, but I have seen some with more pink, blue and/or green coloring in them.

I have Singer 5 machines with G serial numbers and none are that messed up. Here is an picture of my 1918 model 15-30 G serial number.

The 115 takes L type bobbins. I know sometimes modern bobbins will not work on the vintage bobbin winders, but I think some will.

Thank all of you again. So does this mean it is dated 1915? I am curious what the 115 means. Also, to wind the bobbin do you loosen the hand wheel? Seems like I remember having to do that on older type machines.

No, the date that the serial number was allocated was as dunster said = 1920.
The 115 is the model number of your sewing machine.
Yes, you loosen the middle knob (stop motion screw) of the hand wheel to wind a bobbin. The instructions for winding a bobbin are on page 6 of the manual, but if you saved it as a pdf it is page 8 of the manual.

Thanks to all of you for helping me and patiently explaining to me. I have downloaded the manual that I sure do appreciate having.

Glad it worked for you. However, it was brought to my attention that the thread is missing a step after you bring the thread around the tension discs it needs to come up back of the tension thread guard (3, Fig. 11), before going into the check spring. I was going to refer to the manualslib page, but it has a water mark over what needs to be seen. The wayback machine has the same manual as the manualslib and ismacs manual that I linked to previously. Here is the link to the pages of threading the needle - https://archive.org/details/manualso...p?view=theater I will double check but you should be able to see two pages of the manual that have instructions for threading your machine. Okay that is the link. Down in the bottom right you can click on the magnifying glass icon with the plus sign to zoom in a bit.

The two that are together are for screwing a seam guide into. According to someone on another forum they said referring to the back hole "The thirdhole in the bed is for the feed dog spring screw to thread into." and according to https://archive.org/details/manualso...p?view=theater nothing on the bed needs oiling. However, it is recommended to clean the machine with cotton balls and sewing machine oil and nothing with water to ruin any decals.

Here is another picture of threading your machine, even though it says it is for a Model 15 it is the same.

You are so knowledgeable and helpful and I do appreciate your kindness. I went back and checked my threading and you’re right I missed a step but it still sewed a good stitch-lol I remember my grandmother (born 1889) sewing so well on these treadles. She always had a quilt under the needle or in a frame. This machine sews so smoothly. I’m so glad my friend didn’t put it on the curb. Even though it was a 4 hour round trip for me, I told her I was coming to get it. So glad I saved it.

Janey is so knowledgeable about these old machines and so helpful to the rest of us. I always enjoy reading these threads even though I don't have the specific machine mentioned.

I'm glad you rescued this one, Toogie. Have fun with it.
