That is evidently correct
According to what I found, there are three sizes/heights marked "1", "2", or "3".
On the 1911 Forum, the well-known gunsmith, Don Williams, said this regarding height:
...I try to shoot for about .120, though I know that .100 is supposed to be minimum. The #1 lever is the highest lifting of the three common levers, though Colt did make one that was stamped "N" for a while, which did lift it higher. This lever has since been discontinued, and most 'smiths will bend the lever to get more lift.
