Chassis Numbers.

There seems to be some confusion regarding chassis numbers so here's a guide for post war Rover P2s


The chassis number can be found on the chassis next to the steering column (RHD cars).
If you look into the engine bay on the drivers side you will see the steering column crossing over the chassis, at this point the chassis number should be on the main chassis leg (see left picture below).
There should be a 7 digit number and if the vehicle is an original "Export Model" the number will start with the letter "R" for RHD and "L" for LHD

On the bulkhead there is a brass plate (see right picture below) with a Body Number, (this is not the chassis number) this number (if original) will correspond with the last 4 digits of the chassis number.
For example if the chassis number is R6214537 the body number should be 4537.
Below is the Rover chassis number codes for models from 1940 to 1949


Seven-digit numbers, preceded on Export models for 1946-49 by an R or L prefix to denote right hand or left hand drive

First digit                                                    Second digit                                       Third digit
indicates year                                                   indicates model                                        indicates body type
0 = 1940                                                        1 = 10hp                                               1 = Saloon
6 = 1946                                                        2 = 12hp or 60                                     3 = Sports or 4-light Saloon
7 = 1947                                                        3 = 14hp                                               4 = Drophead Coupe
8 = 1948                                                        4 = 16hp or 75                                     5 = Tourer

The last four digits indicate the serial number, commencing from 0001 in each series for each model-year
I'm often asked what colour Tilly has been painted. From what I have been told it is a genuine Rover colour  from almost 20 years after she was built. The colour is Admiralty Blue which was a popular colour for the P5B and other Rovers built between 1966 and 1974. As I have never done any paintwork to the car I cannot  guarantee this is the correct colour
The paint code is as follows.
The original plugs for the Rover P2 would have been Lodge CB14 which are no longer available. A few years ago I managed to obtain 3 of them and thought you might like to see how sparkplugs have moved forward (tongue in cheek) since the 1940s

Lodge plugs came in sealed tin boxes at a cost of 5/- with a warning that if the seal was broken then they should be refused
On first looking at the plugs they donít look too different from modern equivalents but they are.

These plugs can be taken apart to be cleaned and separate into two major components. The insulated top part with the electrode unscrews from the bottom threaded part to make cleaning a simple task.

The part that screws into the cylinder head has not one but three earthing tags.

I can remember around 20 years ago Bosch anouncing the greatest innovation in spark plugs whick was the multi-earth triple tags. They must have forgot that Lodge did it some 40+ years before them
Sadly modern fuels and CB14 spark plugs are not compatible so these 3 plugs will never be used
