Hi Galaxy Flyer -
When I first got the beast on my licence it was recorded as 'Concorde Series 102 & variant'.
(Translates as British-built series plus s/no. 214, aka G-BOAG)
These days it appears as just 'Concorde'. (I'm surprised it still appears at all since the type isn't current on the register).
It's a while since I filed a flt plan for a Concorde sector, but recall that it was entered as 'CONC'.
