I would appreciate it if someone could authoritatively post the precise barrel threading difference between a short and long receiver.

The forearm hanger is originally only soldered to the front of the frame. The screw attachment on Ed's carbine is an owner modification.

I'm not sure what you want to know "precisely" about the threading difference; but there is an long frame old model drawing in Goertz and Sturgess around page 1740 in the red books, and the short chamber drawing is readily available. The length of the barrel that extends into the receiver is 21 mm on the long frame and 19mm on the short frame.
