Short SC1 and Rolls Royce Flying Bedstead

I recently found a few photographs I took at the Fleet Air Arm Museum Yeovilton in 1990. In Hall 4, the one with the Concorde 002, among the displayed aircraft also were the Short SC1 and Rolls Royce “Flying Bedstead” experimental VTOL machines. Since then I have revisited the Museum several times, the last time in 2013, but those interesting machines were not displayed anymore. Could it be that they have moved to the Science Museum in London?
