The answers are
SBS5396B- B45/TL11/2R
Where B45 is the initial model code by Leyland for its
Olympians, SBS5396B is also one of the few Olympian
prototypes to be produced. TL11 means its using a
Leyland TL11 engine while 2R means its a 2 axle right
hand drive bus. It is believed that it is in preservation in the UK
now.
SBS3550K to SBS3571A, SBS6907X to
SBS 6999E and SBS7113M to
SBS7197X- ONTL11/2R
Where ON is the Leyland code for Olympians
SBS9000S to SBS9199C –
ON3R56C18Z4
Where 3 R means its a 3 axle right hand drive bus, 56 is the
production run code, C1 means its using a 10 litre Cummins Engine
(LT10) and Z4 means its using a 4 speed ZF gearbox. The presence of
the 8 is still unknown to me.
SBS9200G to SBS9300B, SBS9301Z to
SBS9400E – YN3RV18Z4
Where YN is the Volvo code for its Olympians, V1 means its using a
10 litres (rounded up, its actually a 9.6 litres engine) Volvo
engine. Volvo seemed to have kept the 8 in the code.
SBS7198T to SBS7297R –
YN2RV18V3.
V3 means its using a 3 speed Voith.
SBS9401T to SBS9600K, SBS9601H to
SBS9670H – OLY-7200
Volvo changed the code for Olympians to simply OLY.
7200 means it has a 7.2m wheelbase.
SBS9800A to SBS9849K, SBS9888Y,
SBS9889U – B10TL-7300
Its partly explained by TIB1224Y above. 7300 means its
has a 7.3m wheelbase
SBS7300P to SBS7449U, SBS7450P to
SBS7499U – B9TL-7220.
7220 means it has a 7.22m wheelbase.
