I examined one of those Pino BB cartridges long ago. There was a customer who wanted to install it but...
Campagnolo taps would not do as they are not designed to be "run through"
A Var tap could make it except that we did not have an extension that would let one grab the tap end as the tap tail passesd beyond the shell end, the tap was not long enough to allow it to be used that way wothout some custom adaptation.
Then there was the conjecture that the original BB shell threading may not have been "clocked" in unison, so as the tap encountered the off side existing threading that region would be rendered useless.
I do not remember Pino provididng a method to do this.
I think the concept to provide a cartridge unit was to keep the bearings in alignment.
