The attached photograph is, I believe, of either Hiller UH12 G-APKY or G-APNR in Fison-Airworks livery. The registration document has the following details. Construction number 784. Registered to Fison-Airwork 20/6/1958. There was a change of ownership 1/1/1961 to Airworks (Helicopters) Ltd., at their address in Redhill.
Sadly there are no Hiller UH12 A's, B's, or C's, left on the UK register. Those still flying in the UK are all now N registration.
Both hulls still exist, and are owned by Vanguard Helicopters Ltd at Henstridge, UK.
I hope the information is useful to your research.

ps. Having spent a considerable amount of time on trying to attach a photograph, I have failed. If you would like a copy, contact me.
Thanks,
Robert.
