I was sent an email from Mr Anderson I cut & pasted it below.
Please reply with an email address that I can send two attachments to you, one 620 kbytes in size, and the other 208 kbytes. What I did was find the photograph that Don Robertson, Jr., had first sent me, which is an actual older 3x5 photograph (and not a "modern" print made by digital reproduction like at the corner drugstore), and rescanned just the area of the tail of the other plane at 1200 dpi. The two files I want to send you are BMP images, one in "true color" (although the original print is B&W) and the other is grayscale. Maybe you or your modeler friends can do something with Photoshop or another program to enhance one of these while we are waiting to hear more from Don Robertson, Jr. The middle digit, a 5, is clearly evident, but hard to tell the others without enhancement, which I'm not set to do.

OK here are the two pictures.
Grey.
True.
With what little ability I have to enhance these pictures I feel confident of the first three digits.
Spotlight.
All I did on the next two was play with lighting and shadow plus zooming in & out to find the best look & then I added the numbers over the top of the plane Numbers until I found the best match. Then I just slid them down under the original numbers & saved them at that position. The spacing of the numbers is not quite the same because I think the rudder is kicked to one side a little to the vertical fin.
True.
Grey.
Any way that is what I have come up with so far the last digit looks like a 3 but I would not bet any money on it.
Well the rest of you take a stab at it see what you get.
