Chassis numbering system, up to July 1970

Suffix letters
Chassis Number Format, from July 1970 on
Product Code; Serial Number; Service Code
Trim Codes and Paint Codes
All early Imps have a B prefix (as an 'A' denotes period 1950 - 1959 and prefix letter 'B' denotes model period 1960 - 1969). From '69 on, Imps lost their prefix.
(Prefix letters 'LB' indicate Linwood manufacture.)
The first three figures indicate the model. The next six digits are the Serial Number.
(If a car was exported in C.K.D. form (completely knocked down) then a 9 was put after the product code.)
Mark / Type | 'Rootes' | sometimes | 'Chrysler' (from '69 on) | announced | last car (maybe) |
---|---|---|---|---|---|
(basic) Hillman Imp | 423 | ||||
Hillman Imp Mk I | 421 | 429 | |||
Hillman Imp de Luxe Mk I | 411 | 419 | |||
Hillman Imp de Luxe Mk II | 412 | 413 | |||
Hillman Imp Super | 442 | 443 | |||

Singer Chamois Mk II | 543 ? | 732 ? | 733 | '70 Apr. B733006587 | |
Singer Chamois Sport | 792 | 793 | '69: 548 | ||
Singer Chamois Coupe | 721 | 722 | '69: 940 | ||
Sunbeam Imp Sport | 492 | 493 | |||
Sunbeam Sport | 593 | L5 593 139499 | |||
Sunbeam Chamois | 733 ? | 543 ? | |||
Sunbeam Chamois Coupe | 523 | ||||
Sunbeam Stiletto | 301 | 302 | 4835 | ||
Sunbeam Californian | 401 |
Example: a Dutch owned Sunbeam Chamois (1969 Feb) may have the following chassis number B 733 000683 LSO, in which LSO stands for L = left hand drive (export); S = Saloon; O = standard
However, a Stiletto that I know (1970 July) has no. LB 302 003034 LCO - Therefore C does not only stand for convertible but assumeably for coupé as well...
Richard McIntosh, Wed, 24 Jul 2013:
the best Imps of all are the B492-series Sunbeams ... especially after the front suspension had been amended. Very few of these are left. As the best ever Imp (in my opinion) there should be even more text dedicated to them ...
A new vehicle identification format was introduced in July 1970.
New chassis plate example:
Chassis No. | G 302 631590 | |||
---|---|---|---|---|
Service Code | B SA X | Paint Code | 108 | |
Trim Code | 701 | Type Code | 211 H 4 |
Example: my Stiletto, exported to Holland (1971 March): G 302 631590 BSA.
BSA refers to the Service Code.
There's a Super Imp registered as PPR 276R on 1 December 1976 with chassis no. RICBA6L103422
Peter Fitzgerald has a 75 Super with Vin number R1CBA5L113581 and a service number which conforms to the L5 443 113581 BSAH format.
Most R registered Imps are Caledonians.
