BAe project numbers …. stealth projects !?!

Does anyone know which BAe project number was reserved for the Replica ??? … like P.1227 for a further Harrier II development (see http://www.harrier.org.uk/history/projects.htm) and so on !

If You follow this list – even as these are all VTOL os V/STOL-projects – there are two Stealth projects listed:

P.1240 Stealth ASTOVL 1 x vectored thrust reverse engine installation * 1987 Swept wing with tip fins

P.1241 Stealth ASTOVL with RALS 1 x RALS * 1987 Delta wing, dorsal intake

Also in Tony Buttler’s books: “British Secret projects – Jet Bombers since 1949” (page 207) and “British Secret projects – Jet Fighters since 1950” (page 162) in the BAe – Brough listing there are four different stealth designs:

P.169 Stealth penetration aircraft – ?? – still secret
P.170 Light attack aircraft – 11.82 – still secret
P.171 Technology demonstrator – 11.83 – still secret
P.173 Advanced Stealth configuration studies – ?? – still secret

Does anyone have some more information ???
