Section 06
Identification
The commission plate on the scuttle/bulkhead is the most reliable way to identify a Stag. It carries the commission number, paint code and trim code. Use that number — not styling cues — to place a car in the production run.
The commission plate
The plate is riveted to the scuttle/bulkhead beneath the bonnet, on the passenger side. It is the car's factory identity card and should match the paperwork.
- Commission number
- The build-sequence number used to date the car and verify its place in the production run.
- Paint code
- The factory colour. Earlier cars use two/three-digit numeric codes; from March 1977 the system changed to three-letter codes.
- Trim code
- The interior trim specification. Cross-reference this with the Stag Owners Club records.
Always verify a car's exact specification from the commission plate and the Stag Owners Club register, not by eye alone.
Commission-number guide
The ranges below are drawn from the Stag Owners Club's records and are approximate at the boundaries. They are the same ranges used on the Mk1 vs Mk2 page.
| Commission range | Model year | Enthusiast designation |
|---|---|---|
| 1 – ~3,900 | 1970 pre-production & 1971 | Early / "Mk1" |
| 10,001 – 14,158 | 1972 model year | "Mk1" |
| 20,001 – 25,432 | 1973 model year | Early "Mk2" — matt-black tail panel & sills |
| 30,001 – 36,714 | 1974 / 75 model year | "Mk2" |

The Stag was unusual for Triumph in offering several metallics alongside its solid colours. The exact shade and code for a particular car should be taken from the commission plate, not from photographs or memory.
Solids
- Pimento Red
- British Racing Green
- Carmine Red

- Java Green
- Topaz Orange

- Astral Blue
- Tara Green
- Midas Gold

Paint-code change: in March 1977 Triumph switched from two/three-digit numeric paint codes to three-letter codes (the first letter denotes the colour group). Late cars may therefore carry letter codes on the commission plate rather than numbers.
Commission-number decoder
Enter a commission number to see which published production range it falls into. This is an indicative guide only — it is not a lookup of that individual car's factory record.
For the authoritative history of a specific car, contact the Stag Owners Club with the commission number, chassis number and any paperwork.
