Is it sharp on the edge of the cut out?? Could it be for cutting the thread??

No not sharp at all . Probably another reason why it's designed that way .

7-11 is a bookbinder with a long stitch & reverse,flat foot that doesn't walk.This machine has a vibrating foot on it.Which I've seen on other models like the 7-25 which has a large shuttle like the 7-31,33.

You were definitely correct. A lot of the parts are matching from the 7-25 part list. I couldn’t really find any other info on the 7-25, like what they were used for and there capabilities. I did end up ordering some large 7-31 bobbins because they also had matching part numbers in the manual. Any other info would be awesome!

Does your machine have a large bobbin machine?The 7-25 base by the needle plate is built-up for the larger bobbin,unlike yours in the pic.

It looks like it, I could be wrong though.

It's hard to tell for sure in this pic.The big bobbin measures 1-1/2"x1-1/2",small is 7/8"x1-1/8"

That whole machine needs a good soaking in Evapo-Rust!!

There is a guy on Ebay UK selling parts for the class 7 machine? you don´t see them that often, He seemingly has a few boxes of parts for that machine so it might be worth while asking him??

Didn’t mean to take so long to reply. I kinda jumped the gun on ordering it and I guess it ended up being the short bobbin. It has a 25mm or 1 inch diameter. The part number on the hook is unfortunately ground down too much. The case has #19977. This leads me to believe that #11910 is the actual bobbin. So 7-9 fits a little better.

It looked like a small bobbin to me.But the race looked like a large one!
