However I cannot find any photos of the later model cockpit.
Therefore I guess for M-4
Now that the requisite 24 Hrs have passed since I posted, I can say yes to your assumption that it is a Douglas M-4
I was hoping it might prove a little harder to find because as you say, photos of the later Douglas DAM's types are hard to find! and the M-2 cockpit you found doesn't have much in common to the M-4 except one particular instrument! True the basic panel shape is correct, but even the cutout for the throttle linkage is reversed, so very well done!
