I'd recommend: -
RAF Museum, Duxford (Cambridgeshire, England)
- Huge WW2 collection.
Shuttleworth Trust, Old Warden (Bedfordshire, England)
- Old aircraft, up to and including WW2, all in flying condition.
Fleet Air Arm Museum, Yeovilton (Somerset, England)
- Royal Navy Collection, large WW2 collection included.
