I have a decent Frankenstellation:
Paid very little for this, it was my first vintage Constellation. Movement is a cal. 501. Case ref. 2852-5. I did a lot of research on similar watches and figured out that the case is likely original to the movement and that started out as a 19 jewel chronometer movement. Someone replaced the rotor assembly with the correct part from a later 20 jewel cal. 501. I later replaced the crown with a proper 10-sider.
Pretty decent redial also. It has a gold starburst pattern, which is not correct for this vintage, but looks nice anyway.
Take care,
