Thanks Paul,
I had a look at this site which is very interesting. Two police supervision launches are shown which are on the lines of ‘MM417 Telecta’ (plans still available from myhobbystore). They are John Harriot (1947-1963) and Patrick Colquhoun (1963-2003). A single engine trainer is shown, which is on the same lines as the Veron craft, with more updated livery and fluorescent lettering.
I have managed to locate the colour scheme, and found the horns still to be available! It would still be nice to see a photo of an original model, so my search will continue.
I went to the local model shop (now becoming harder to find), bought the first pieces of balsa, located graphite paper to transfer the shapes from the plan and made a start. I am not the fastest of builders, other chores seem to take priority. The size and construction methods, of this launch, fit the bill. i.e. kitchen table build, no fibreglass and 1970’s retro.
Thanks again Tony
