Probably going to be upside down if you try to part it out. Might be better to look for a correct case on eBay.
It depends on the physical and aesthetic condition of the movement, but I've seen good cal 561 movements sell for around 250 - 300 on eBay. Hands are worth something for those who have dials with onyx inserts and dial has value too. There are always collectors about who are looking for good parts movements. Cheers Desmond
