As mentioned above, there are several different versions of this mechanism. For example, [[Waterman]], in order to circumvent [[Sheaffer]]'s patent, introduced, based on Barnes's patent, a lever pivoted directly inside a metal cage that contained the entire mechanism. This in turn was fixed with fins to the pen, using as housing a special slit created in the barrel side.
