Litschert Power Boosters were made to convert lower magnification 3/4", 7/8", and 1" tube scopes to 6x or 8x "varmint" scopes. I have a couple of scopes that have them installed and think that they were sort of an era specific "patch" that was more "sizzle" then "steak". The idea being that you could unscrew the objective housing on your Lyman Alaskan or Weaver K2.5, screw on the Litscher unit, and go varmint hunting with a higher magnification scope.

I disagree about the "patch" or "more sizzle than steak" comments.
You have to remember the era from which those power booster units came.
From about 1945 to 1955 there were VERY FEW light, affordable internal adjustment scopes that were over 4x. Also until the late 1950s, most scopes were not fogged proofed and nirogen filled. So really , adding the power booster was a convenient and viable conversion.
Increasing magnifaction by adding one of those untis to an existing scope was no more frivolous to a shooter of that time than a rifle owner of today replacing a wooden stock with a synthetic. It only improved the performance of the scope if the shooter could handle the higher magnification.
Basically, as the 1950s drew to a close, Weaver, Leupold and Redfield and Bushnell all had nice 6, 8 and 10x scopes on the market which made the power boosters pretty much obsolete.
Also, as scopes became fogged proofed and sealed, such owner installed conversions fell out of favor.
