Triumph Spitfires can be identified by a number of different distinguishing marks: commission (chassis) numbers, engine numbers, trim and paint codes. And to some extent even by the engraving on the windscreen.
The car's commission (chassis) number can be found on an aluminium plate riveted on the left hand bulkhead panel (non-USA models) or on a plate attached inside the left hand doorframe (USA models). Note: cars originally imported into the Netherlands have the commission number also stamped on the right hand chassis outrigger, just ahead of the bulkhead.

The number stamped on the little body colour plate riveted below the commission number plate on European cars is the body serial number. This is never the same as the commission number.

Spitfires produced after October 1979 did not have commission numbers, but standardised VIN's. VIN is short for Vehicle Identification Number. These were composed of five letters, one digit, two letters and another six digits. The meaning of all this is as follows:

First letter Always 'T' for Triumph
Second letter Always 'F' for Spitfire
Third letter 'A' for European market
'L' for Canadian market
'V' for US federal market
'Z' for US Californian market
Fourth letter Always 'D' for Drophead - even if supplied with a hardtop
Fifth letter Always 'W' for 1,493cc engine
Number '1' for RHD without overdrive
'2' for LHD without overdrive
'5' for RHD with overdrive
'6' for LHD with overdrive
Letter 'A' for 1979 and 1980 models
Letter Always 'T' - assembled at Canley
Six digits Production number, last one being 009898

The VIN can be found on the commission number plate. In addition to this, the very last cars had them stamped in the right hand boot gutter.

Commission number prefix and suffix codes
Prefix Suffix
FH- All markets, except USA & Sweden
FK- USA 1300cc models
FM- USA 1500cc models
FL- Sweden only
C- USA (complies with Californian legislation)
U- USA (complies with Federal US legislation)
L- Left Hand Drive
O- Overdrive fitted

On a standard Spitfire engine, you will find the engine number stamped on the top left hand side of the engine block, just below the Nr.4 sparkplug.

To be sure it's the proper engine (but not necessarily the original engine that was installed when the car was produced), the engine number in a Euro-spec Spit 1500 should always have the prefix ' FM'. If it says 'FH', it's a 1300cc MkIV engine. If it's a MkIV you're looking at, that'll be fine.

Over the years, many (early) cars have been fitted with non-original engines from other Triumph models. The following information may be helpful in determining what a replacement engine really is.

Here's an obscure little trick to determine the approximate production date of a Spitfire, or at least its windscreen.

Find the etched logo on the windscreen, most probably in one of the bottom corners, that says 'Triplex Toughened' or 'Triplex Laminated'. Firstly, determine the year of manufacture by checking which letter in the printed logo on the glass has a dot under it. (You need to know the decade as this can't be determined):

Toughened    or    Laminated
..........         ..........
1234567890         1234567890

next find the month of manufacture by looking at the dots over word 'Triplex':

       .                                       :    .
Jan    TRIPLEX (dot over the T)        Jul     TRIPLEX

        .                                      :     .
Feb    TRIPLEX (dot over the R)        Aug     TRIPLEX

         .                                     .     :
Mar    TRIPLEX                         Sep     TRIPLEX

          .                                     .    :
Apr    TRIPLEX                         Oct     TRIPLEX

       :                                            .:
May    TRIPLEX (double dot over T)     Nov     TRIPLEX

       :.                                            :
Jun    TRIPLEX                         Dec     TRIPLEX

Thus, a Spitfire with a windscreen marked

.     :

indicates that the glass was produced in September 1974 (because it couldn't be 1964 or 1984).

The windscreen on my own car shows:

.     :

So the glass in my car was produced in September 1976.

Note: this is not a reliable way of determining a car's age, since the windscreen may have been replaced at some time.
