Oh! Just remembered! The alloy handlebar stem was also interesting in that it had a star cast into it !
The Weinmann alloy side pull brake calipers seem to have been original equipment as they were manufactured around that period .
It had a Sturmey Archer ? Rear hub, number of years unknown . The model differed from the previous 2 in having fluted ends to the seat stays .
The 2 bikes pictured must date from post 1950 according to the type of brake calipers fitted GB Coureur as that was the earliest date they were introduced .
