Once I measure dimensions I use mm paper to make large drawing and then just measure angle.
European angles are 60, 65, 70 and 75 for most of the gun industry. So if you measure 63.5 for some reason that should be actually 65.

Or you can use known dimensions to calculate angle with given formula which brings us to 67.5 angle for the front post male dovetail.
