Ken:
Browsing through the unknown category I can say that the following photographs are aircraft which already have existing profiles:
AC483345 is Sea Fury T20 F-AZXL
AC483459 is F/A-18C J-5017
AC483468 is Hunter F58 HB-RVU
AC483487 is DC-6B N996DM
AC483494 is PZL Kruk D-FOAB
AC483533 is Bf-109G D-FWME
AC483534 is Me-262A D-IMTT
AC483535 is also D-FWME
AC483536 is also D-IMTT
AC483537 is also D-IMTT
AC483538 is MD.311 Flamant F-AZKT
AC483539 is JAS-39C 39278
Perhaps you can fix these and thereby reduce the number of "unknowns".
