RILEY - CHASSIS NUMBERSas Old as the Industry, as modern as the Hour
This page is intended to explain how to Decipher the Chassis Numbers used by Riley.
I have taken the following Data from David Styles excellent book, 'As old as the Industry', and hope I haven't breached any copyright! If anyone knows any different to what is set out below, I would be grateful if they could correct me!
|1896-1907||100-??||Bikes, Tricars and Quads.
The Frame Number was stamped on the frame, and ran sequentially, without any model differentiation.
|1905-14||?||all V-Twin and 17/30hp cars.
Again, it appears that all models had sequential numbers, probably continuing with the series from above.
Sidevalve (10.8, 11/40 & 11.9) Cars.
C286- (3/4 digit)
|10.8 and 11/40 cars.
After 1922 a Letter suffix was added to the engine number showing the bodystyle the engine originally powered!:
|1925-28||69xxxx||All 11.9 Cars (69mm=cylinder bore).
The engine numbers are again thought to all have a model suffix, as above, with one addition:
|With the Launch of the 11.9 in 1925, and the 9 in late 1926, Riley Chassis Numbering started to get more organised, with at least a differentiation of which engine the car used. With the Riley 9 Chassis, there are also enough cars and records surviving to be able to provide an approximate yearly breakdown:
|July 1926 - Oct. 1930||600001-601000||MkI Chassis, RH Gearchange, Cone Clutch.
|601001-602964||MkII Chassis (MkI body)|
|602965-604293||MkIII Chassis (MkI body)|

Monaco II body from C/No 606770
|1927-28||60/1 - 60/?||First 9hp Speed models (Brooklands) built by Thompson & Taylor Ltd.|
|1928-32||8001-8093?||Brooklands Speed Model.
There are suggestions that the last Brooklands Chassis Number was 8098, but evidence to date only goes as far as 8093.

|Oct. 1934-||22T 101-2199||Kestrel Lynx & Falcon, 1935 series.|
All Models July / Aug. 1935 onwards.
From Summer 1935, Riley employed a new Chassis Numbering System, which not only identified the engine, but also the Year and Bodystyle originally fitted. This system continued into the postwar RM series, albeit with a few minor anomalies along the way!
The General style was thus:
SS 3 8 A X 1234
The S / SS identifies the engine tune:
The 3 identifies the engine itself:
(Nuffield) Riley 16hp engine for 49.
The 8 identifies the year:
The A identifies the bodystyle:
16/4 Continental / chassis.
The X identifies a Car with Overdrive, standard on Big 4's, a rare option on other models.
1234 is the chassis number, numbered sequentially through each engine type, regardless of the actual chassis type.
All Cars post July 1935
Just to clarify the details above, the following Chassis numbers were issued from 1935 until production was discontinued in 1940.
