it was just my suggesting,and when you search in Douglas list,you will find many mysteries,such as Model-953 for AMST ?.

I believe that you are referring to the Boeing 953 military transport family; the Model 953-280 was the starting point for the YC-14 AMST.

In the Douglas series, "953" is in the midst of reserved numbers for "Advanced Commercial Transport Studies".

You have previously reported McDonnell Douglas studies leading to the YC-15 AMST as being in the D-915 family http://www.secretprojects.co.uk/forum/index.php/topic,512.msg162759.html#msg162759

SOME INSIGHT INTO DOUGLAS'S EARLIEST MODEL NUMBERS

The earliest Douglas Model number properly identified is "109" (as in DC-1-109). What about the first 108? Did they exist? Were they used at all?

A finding aid recently published on the web has enabled me to lift at least a corner of the veil.
It is entitled The Donald Douglas Collection of Corporate Documents, Engineering Drawings and Library Materials 20-01-07 and was prepared by K. Williams.
Published by the Museum of Flight Archives in Seattle, it is unfortunately full of typos but after some adequate processing and cross-referencing it I have been able to extract some useful data from it.

The second and most interesting part of the 141-page document is entitled "Douglas and Davis-Douglas Company Engineering and Model Drawings" and lists all the company drawings that are part of the museum's collection.

Those two documents are now "dead". Mind uploading them?

Not at all, Ryan, but I'm afraid I could only find the first one on my HD. Here it is:

If I'm not mistaken, D- was for Design, DS- for Design Specification, TS- for Type Specification and SS- for System Specification.
