Unfortunately, this parts machine arrived DOA. Motor is fried, and the parts needed to make the back-space function work on my orange-colored Facit 1840 were also missing on this 1845.
It did yield lots of springs, nuts, screws, washers, main-spring, air-brake, and lots of other plastic parts as spares for my 1840 machine.
Still worth the $ 25 total. It was a good gamble.
