Adrian,
Aviation Workshop has announced some detail sets for the Airfix TSR.2, that include pylons and tanks among other goodies! Here are the details, but no prices yet. The last info received stated that these will be available late May:
BCS-708 1/48 Scale TSR.2 Set 1 - Extended Nosewheel leg, weapon pylons and 1,000lb Mk.N1 bombs.
BCS-709 1/48 Scale TSR.2 Set 2 - Detachable in-flight refuelling probe, 1,435 gallon Ventral drop tank, 450 gallon drop tanks and pylons.
BCS-710 1/48 Scale TSR.2 Set 3 - WE177B Bombs and new weapon bay insert.
BCS-711 1/48 Scale TSR.2 Set 4 - Blue Water missiles and pylons.
BCS-712 1/48 Scale TSR.2 Set 5 - Reconnaissance Pack.
Sounds very good to me and these bits will go well with my "What-If" decals! HTH,
Rick
