I have deleted the second CAA profile and the two profiles are no longer linked.
Same old problem!
FAA = Stinson V77 cn 77381
CAA = Stinson V-77 cn 77-381
I have requested a registration cross reference note to be added to each profile.
Your image from Dupage dated 1990-09-15 is prior to the FAA de-registration and I have moved it from G-BUCH to N9570H
