337 Camera port

[kevin]

Rob Wooding asked me to post the following for him:

We are looking for a source of approved drawings for the
installation of a photogrammetric camera port in a 337.
Turbo or Pressurized model. Quite a few aircraft were
modified in this way although it was not a factory option
as far as I can tell. Any ideas?
