Indeed she is. First prototype was G-ARYA and third prototype, G-ARYC, is preserved in much more complete form at Salisbury Hall.

I was lead to believe that G-ARYA and G-ARYB were both the first and second prototype airframes. Their was no third prototype airframe as such.

G-ARYC was the first pre-production Series 1 airframe, which had played a major part in the development of the Viper engine.

It is right what Les has said about us working on G-ARYB. It is intended to be used as a demonstrator for schools. Work is still going on frantically, but she is coming on fine.
