Yes, you can tell which specific typewriter was used to type something so long as there is either a slight defect (for lack of a better term) if two letters are closer to/further from each other or a letter is a little higher/lower than it normally is.
PLUS, because different people hit the keys with different amounts of force, each machine wears out at different rates and so the keys wear out at different speeds, so there’ll be different wear patterns to the keys.
