Here is my newest find. This Necchi is in really rough exterior condition. Not as bad as some that Billy rescues. But the paint is crazed and falling off over the entire machine. There is some rust but not too bad. Everything moves pretty freely. The wiring is shot so may take your advice and treadle her. The cabinet is very nice, just needs to be waxed and shined up. It weighs a ton!
I think it is a model BU. Serial #U199726. Cast on base is Italy 25004.
If I win the lottory I will send it to Billy for a snazzy paint job.
