I may have access to such a program (and more importantly, someone who knows what he's doing with it).
Let me see what I can do with a few of these pictures. As long as the airfoil templates are known, the rest may not be super difficult to recreate.

Need to make allowance for Vanishing Point & Lense - depth effect .
Four Differant Photos & youll get Four differant Moments ( Hinge to Hinge ) scaleing enlargements manually ,
working from known dimensions .
Theres a lot of 3 in root chord , two in. tip chord tailplanes & elevators & 3 in - 1 in Flaps ,
But the depth perception gives varying results . Wonder if theres a programe foe Lense Type Effect ,
A lot of older magazine covers stated the Camera/ Lense in the write up .
And Known photographers had known lenses .
Getting a bit tecnical ?
Establish vanishing point and establish miscilaeneous parrallel lines , doing it long hand , gets you started .
With hopefully a ceterline started at the spinner center / prop shaft .
Withing 14 microns should do it .
No No . measure twice - cut once . Within a quater inch will do . ( Builder Baloney -
If you want to start a builder , state Dimn. to three decimal places , or when asked if its all right ;
say ' Ive cut it twice and its still to short . This gets their attention smartly .
)
Just model aerplanes ,
so total exactitude isnt necceassarilly vital to the survival of the species here,
but known engines etc have known dimensions , so its good enough to do a fair & reasonable approximation .
Tho a True Replica ' is just that , so Stateing on the Drawing the source/ method , is fairer .
A Bank of old transfers / Numbers etc And Their Dimensions would be usefull fore ' decoding ' photographs !
WHAT is the Size of the 76 W. C. scrutineering sticker ?? to within 1/2 mm would be fine, thanks .
