Sid did have a Short s16 Scion and it was sold to the Strathallen collection in Scotland some time ago. When that collection was sold it was aquired by the Ulster Folk and Transport Museum at Cultra in Northern Ireland. Unfortunatly that group is more interested in traditional musical intruments and hand knitted shawls rather that aeroplanes and so it is sitting in a shed close to the Belfast Lough and the Aluminium in the structure is slowly decaying.
The aeroplane on the right seems to have an inverted engine and could be a moth or interestingly a Genairco which was around at thast time.
Other lighties that he had were the Westland Widgeon which was restored by John Gallagher for Dick Smith and now resides in Dick's home at Bowylie . There is an Avro Cadet which was restored by Clin Ashton-Martin and flew recently in the 90th anniversary pagent /pilgimage of the RAAF. At one stage he also had a Foxmoth.
There is a Scion being worked on all be it slowly because of other vintage aeroplane projects and if anyone is interested please let me know.
He also had a Comper Swift VH-UVC which is in the process of being restored with its Pobjoy engine. The Scion also had twin Pobjoys and these present a little difficulty.
