Can't say with any 100% guarantee, but I've yet to see any British headset that was not meant to be installed with an interference / tight fit, requiring it to be pressed in.

What you do come across though, are plenty of examples of poorly installed headsets, with slack cups and/or crown races - maybe a lot to do with the manufacturing tolerances in those days, especially when the headsets been replaced since being first installed with one differing from the original make or type.

A fix - or should that be bodge was to have the cups brazed onto the headtube. Creates no problem with those headsets like some Brampton's with a separate race that can be renewed at a later date, but a nightmare otherwise especially 50+ years down the line.
