First off, the Model 1917 and P-14 bolts have "dog leg" handles, so they are obvious. To tell the difference, look at the extractor. If the hook is as wide as the body of the extractor, it is an M1917 bolt; if the hook is narrower than the rest of the extractor, it is a Pattern 1914 bolt.
The Springfield bolt has a safety lug and the handle is bent down in a sraight manner; the safety reads "SAFE" and "READY". The Mauser bolt handle will either be straight (sticks out straight from the side of the rifle) or be bent down in an curve (a K.98k bolt handle is bent down; most other Mauser bolts are straight).
The above is pretty basic, and there is a lot more, but hope this helps.
