I don't think this is an "ED" type.
"ED" stands for "Enclosed Gear, Deering binding attachment"
This one being marked Deering seems to have been made prior to the "McCormick Deering" marked machines. (1923 -'47)...and I don't see any enclosed gears.
Plus, on the McCormick-Deerings, they had gone onto a simpler plan for driving the reel.
I still say like in my last post, this is between 1902 and prior to 1923, possibly prior to 1908 as well.
We have two 'ED' machines, (In sad state!) and neither has pneumatic tyres, which it seems were brought out by IH with the PTO drive.
