I have several Newtons, mostly Model 1916, but with one Model 1922, made in Germany by J.P. Sauer on an Oberndorf Mauser action, with a unique Newton set trigger. All of the 1916's are "take down".
I have never owned a Model 1924, I guess because I couldn't stomach the dog leg bolt handle.
Since the 1924's share the same type of bottom metal as the 1916's, I assume that the "take down" feature consists of using the hinged floor plate as a handle to release the front of the action. The rear of the action is secured with a hook type arrangement, similar to that of an M1 carbine, so that the barreled action separates from the stock without the use of a tool. It is an ingenious system and superior to those which require the barrel to be separated from the action, IMHO.
