Thats right I am trying to get rid of some of these parts machines so I can make room for all of these new parts I have for the vintage machines.
I am parting out a few Singer 27's, and a Wheeler and Wilson D9. They all have good needle bars, presserfoot bars, hand wheels, connecting hardware, mechanics, face plates, presser feet, thumb screws, you name it. All Singer machines have proprietary thread pitch so this might be a chance for you to get the one screw that you have been looking for.
If you need anything just let me know and I can get you a price and I will be digging out more machines as I get further into it so keep an eye on this thread!!
