We have come across an original wright " flyer" ID plate that says
Type "D" Number "1". We don't believe it is from the later (Model D)
types (two of them) given to the Army as SC 19 and SC 20. We have
found one paragraph where a military official Arnold was talking to
Orville about a plane plane he refers to as a WrightD had great
difficulty in meeting the tests apparently because of structural
defects and underpowered engine. Arnold told Orville the Signal corp
needed to purchase the light scout airplane (Model D). which he wanted
the Army signal corp to purchase from Orville. So the Scouts are not
the same as the flyer WrightD and we don't know if our plate is from
the WrightD or another D. We can not find much info on this model
anywhere in our research.We can email you a copy of the plate if you
wish if you think it might help. Thanks. Botman.
