Hi,
I am the administrator for a site called Alec Wortley Helicopters. On the site are a number of old photos, press articles, letters, invoices etc. relating to the two Bell 47 G3B1 helicopters that this company owned and operated between 1979 and 1983. The two helicopters were G-CHOP and G-BGMU, both ex-military and both still airworthy. There are also a few pictures of Bell 206Bs and Westland Scouts. The URL is
