No sewing machine is included.
The part/s were taken from Toyota Electronic Sewing Machine FSG 325 (see last 2 pictures).
To cover the Bobbin Shuttle Race Hook area. It has a small metal piece(see 2nd picture) to attach to the main body.
I believe the part/s will fit other similar sewing machine, but please check your sewing machine.
If you have questions regarding the item(s), please ask; we'll try to answer, but there might be a delay in response due to time restraint. We apologize for that.
Thank you.
