Forgive me if I have raised this previously!
Among all makes of self builds, it is common to use the numeral "1" for the serial number, and the profiles are differentiated by the builders name.
Correcting this to "Rutan" results in the possibility of incorrect linkage.
Of the 894 "Rutan Long-EZ" in the database, 30 have the serial "1".
To avoid linkage, I am adding the registration in brackets to the serial field.
This also applies to other numerals such as 01, 001, etc and of course to other numerous self builds.
