Not sure of the head set it was a steep headset the races were integrated into the lugs. the BB is TA with BSA fluted cranks and the rear track hub is a steel Union(german) hub.Stem and bars are GB Saddle is brooks on an Alum post. Front hun is 80s japan sunshine and reams are track rims made in Argentina
Headset appears it may be the integral version of the Brampton Alatet. The serrated lockwasher likely exhibits the Alatet name.
Here is a Brampton catalogue from 1948 in case you are curious. The head parts covered are listed in an unusual way - by application/placement rather than in sets. So there is a page for locknuts, one for lockwashers, one for fork crown races, etc.
The rims are Saavedra Feather Weight rims. Saavedra made pots and pans when they sponsored a racing team the factory developed a line of bicycle parts. Rims and headsets maybe other parts too . When they dropped bicycle racing and stopped making parts there was a dump on ebay of their parts.
