1964 WCML Sleeper Formation

[d9009alycidon]

I have been browsing Robert Carrolls superb Carriage Formation Notices and noticed an intriguing sleeper formation. In the winter 1964-65 book the 9:50 (SX) London Euston to Glasgow Central and 10:45 Glasgow Central to Euston is shown as being formed of 10 Sleeper Firsts, 2 BGs and a Pullman Car. Now the Hadrian Bar didn't get rebranded as the Nightcap Bar and transferred to WCML sleeper working until 1969 if my online sources are correct, so can anyone advise which Pullman Car was used in this service in 1964/65? Looking to Model some Sleeper formations from this era so would like some degree of accuracy

Thanks

There must have been another similar car as obviously two were required each night for north and southbound trains.
I do remember seeing it as a child on the opposite platform whilst boarding the Glasgow to Birmingham Sleeper which in that era departed at 11.15pm.
