Standard Rotary bobbin case
 

Hi there, I have a Standard Rotary treadle machine and I looking for a bobbin case for it. The original part number is 3626BA. I would love to get this up and running. Any help would be appreciated. Thanks! I have a picture from the original manual but cant seem to figure out how to post it here.

It will be tough to help without a picture, here are Ourworkbench's AKA Janey instructions on posting pictures.

We like pictures. In order to post pictures on Quilting Board, you will probably need to reduce or compress the picture to a file size that is smaller than 2MB. How to post images can be found at https://www.quiltingboard.com/attach...020-01-17-.pdf
Don't forget to scroll over to the far right to find and click on the "Upload" button.

I have found that only the big red "Reply" button or "Quote" work to give me the paper clip icon to work for adding pictures.

Or simply - Make sure pictures are smaller than 2MB

Click on the paper clip icon
Click browse - choose picture/s. (only 5 allowed per post)
Once they show up as being loaded, Scroll over to the right side and click on "Upload"
After the pictures show up as being attached, you can close that window and go back to the screen to finish posting your post.

This may be a long shot, but in a local thrift store there was a machine badged "Standard", leaf tension, but a rotary machine as opposed to a vibrating shuttle. It was a "treadle only" machine, and only $3, but I didn't buy it as it was missing the bobbin case. I looked on my Boye needle dispenser to see what needle a Standard used and it said Boye 2 1/2, which is the CC1221, which goes with the New Home/Free Westinghouse rotaries I have owned:

And this machine also

So I was going to buy the machine but it was gone when I returned to the store. My plan was to try a bobbin case from a machine I have that uses the Boye 2 1/2 (CC1221) needle.

Needlebar.org does not have a lot of information on Standard

but it does show multiple bobbins for the rotary, so as I said, my plan may have been a long shot.
