Wow, that's an interesting machine! Not sure what's going on with all that springy stuff up top - would like to see it in action.
It's amazing how well some of these have survived. Kind of sad to think machines being made now simply will not last; vintage sewing machine lovers of the future are basically going to be collecting all the same machines we are, since that's just about all that'll survive in a functional way. They'll have pictures and videos of our modern machines, but just crumbling plastic hulks in the real world.
