As above, the MOY test is just one item to look at and depending on the Constellation it may not prove a good dial/ redial.
You need to look at the dial as a hole.
This one screams ‘off’ at 10 paces but you’re not necessarily going to know that yet.
So look at the individual parts separately to get a feel for its authenticity.
E.g have you ever seen another ( authentic) dogleg with the spelling chronometre ?
This spelling doesn’t (legitimately) appear on a dogleg.
