Allen's color, in person, is pretty doggone close to what Viking blue looked like new. Not bad for a replica.
I checked my files and here is some original info that may be of some additional help:
Viking blue was a '62 - '63 Ford/ Mercury color code E.
It was
NOT the Lincoln or T-Bird code E, which is different.
The NAPA/ Martin Senour cross-reference is 30Y-3233.
The Sherwin-Williams cross-reference is M30-J-1448.
