I never found an imperf of this stamp before
This is only a few years after the switch to perforated stamps and (despite the perforations) many users still cut their stamps apart with scissors.
As another example, a later grilled, Scott 94 on cover
Natural government-cut straight-edge at right and slightly wavy left edge cut by the user. Eye-catching, but it would never get a cert as a part-perf error.
