I know the first gen got the star and the second gen the compass rose, but not sure of the diameters? Any help would be appreciated!

Thanks, Preacher. If it's not too much trouble, would you mind measuring the thickness as well?

For the record, the first gen A277 crown dims are as follows (rounding):
Diameter = 6.4mm
Thickness = 4.6mm
Teeth = 22

Upon reflection, I suppose the diameter would be rounded to either 6.45mm or 6.5mm. Just seems that it is commonly rounded to 6.4mm out there for some reason...
