I think we've lost our way ...
The Gillette/AutoStrop merger was late 1930. Gaisman became GSRC's Chairman.
Roll forward in time to presumably early to mid-1940s and over the pond to Britain. In what would appear to be limited quantities, Gillette produced a minor variant of the twin slot top cap that had short pins which were either symmetrically placed either side of the central post or on a bias, paired with the more regular twin slot flat bottom baseplate. The question is regarding these top caps and their specific purpose when the more regular twin slot would perform the same task and was designed to fit the base plates.
By this point, Gillette blades were the full cutout as per blades we might buy today. Indeed, Gaisman's key patents: 1,633,739 & 1,639,335 were incorporated into the Gillette Blue which was readily available through that period and had been for a good decade. Those patent numbers are on the blade itself. Or, spun the other way around, the Gillette Blue WAS Gaisman's blade, replacing the 'New' blade design. This design has not changed at all since 1934.
Specifically, what then was the purpose of the short pins, either symmetrically placed or on a bias?
I don't think it is about fitting a specfic Gillette blade since Gillette blades now featured the somewhat universal cutout which provided compatibility with a whole range of Gillette and competitors' razors. I don't think it is about fitting the competition's blades (see the period advert on page 2), since the long slot or the twin slot would fit all of those blades as well.
