Hello,
I've brought a Jones Treadle sewing machine (unknown age) and the key for the front is missing. They open but don't stay closed, so I was wondering if anyone knew what type of key it would take?
I've tried my singer hand crank case key and a flathead screwdriver but neither turns the lock.
I'll try and attach some photos

if anyone has any more information about this type of treadle that would also be amazing!
