Field stripping any Model 1911 A1 45 military pistol is the same no matter the manufacture. Rather than try to tell you, here is an excellent link to a video showing how it is done. It is very simple if done correctly. I also own the exact same pistol as yours and treasure it. Mine was made in 1917.
There is no "field stripping" per se. Open the action and clean with rod/brushes/patches.
