Chassis number meaning for a TVR: difficult!

It can be always very useful to know what kind of TVR you’re going to purchase. Even if, from what I learnt from some RHD units who needed an homologation outside UK, not always the VIN number is engraved on the chassis too. So every TVR can be identified from any kind of VIN plate.

Analizing some VIN numbers I found, here is a proposal for a deciphering procedure for any TVR VIN number (consider that I miss example to try to build a correct procedure for Griffiths, Chimaeras and Tamoras):

1,2,3 – SDL: unique TVR id at the beginning of the chassis number
4 – MODEL: C (Cerbera), S (Sagaris), E (Tuscan), F (T350),
5 – ?: C (?), A (?)
6 – fixed digit: 1
7 – ENGINE: 6 (Speed-6 4.000 cc?) or 7 (Speed-6 3.6000 cc?), Cerbera ?
8 – fixed digit: A
9 – CHECK DIGIT: ?
10 – YEAR OF PRODUCTION:  6 (2006), 5 (2005), 4 (2004), 3 (2003)…
11 – fixed digit: B
12 – fixed digit: 0
13 – fixed digit: 0
14- fixed digit: 1
15,16,17: BUILD NUMBER

Example 1: SDLSA16A16B001121. TVR Sagaris LHD built in 2006, unit n. 121 of 2006.
Example 2: SDLSA16A16B001135. TVR Sagaris LHD built in 2006, unit n. 135 of 2006.
Example 3: SDLEA17A43B001492. TVR Tuscan 3.6 MK1 LHD built in 2003, unit n.492 of 2003
Example 4: SDLEA16A63B001270. TVR Tuscan S 4.0 MK1 LHD built in 2003, unit n. 270 of 2003
Example 5: SDLEA16A85B001127. TVR Tuscan S 4.0 MK2 LHD built in 2005, unit n. 127 of 2005

I found that early TVR Cerberas have a different VIN Number:

Example: SDL FAC2 P [1 to 10 or x] T B 01 1234

SDL: common digits to all TVRs
FAC2, Vehicle Type: FAC2 (4.2 AJP CERBERA-CAT), FAC5 (4.5 AJP CERBERA GT-CAT), FAN2 (4.2 AJP CERBERA -NON-CAT), FAN5 (4.5 AJP CERBERA GT-NON-CAT).
1 to 10 or x: internal check digit that can tell if the chassis number is a genuine one
T, year: L (1990), M (1991), N (1992), P (1993), R (1994), S (1995), T (1996), V (1997), W (1998), X (1999), Y (2000).
A, build month: A=Jan B=Feb etc. Except I
0, not used for any purpose.
1, not used for any purpose.
The last four digits are the sequential build number for the Year starting at 1000.

Any help? Any suggestion? Any error you found? Write me an email at info@tvrblog.com. If we could find a unique procedure for all TVRs, at least starting from TVR Chimaeras, it would be a great help for any TVR lover.
