I am not professional tailor.,but I was able to thread this machine without any problem in less then 5 min.I tested it and it works.You will need to do some basic adjustments because I can see top thread on the bottom of the material along with bottom stitch.Top stitch comes perfectly.Also one of the plastic top thread spoons is broken,but I do have that broken spoon piece I will also include.The machine has horizontal bobbin case built in .I will include one bobbin with white case.Machine comes in original Singer plastic case Handle on the case is still there but it is all damaged with rust so it is taped.Case has some scratches ,discoloration and crack on one side.Also case has bottom lock part on one side missing, other side side has both lock parts so it locks well on that side.Machine itself in good condition..It was made in Great Britain.Needle will be in locking position during shipping for safety.You will need to unlock it when you receive it. This machine was also lubricated with oil. Bobbin winder tested and works well. Thank you.Have a nice week
