Hi Ron,

I looked in Thompson's SP book and did not see a match.  The model does not have any drop doors.

Do you have a picture, or some other way we can see what you're describing?  As a total shot in the dark, there was a class of SP gons at about 48' that I think were straight sides.  I built a model of one, perhaps from Speedwitch, but both the model and my SP books are packed so I can't be more specific.
