TS, TSF and TCF commission numbers
Triumph TR2, TR3, TR3A & TR3B Decoder
The early Triumph TR cars are especially well suited to serial-range decoding because the TS sequence has documented breakpoints between TR2, TR3 and TR3A, followed by TSF and TCF for the TR3B.

Early Triumph TR commission numbers
The TR2, TR3 and TR3A share the familiar TS prefix, so the serial portion is essential. PetrolJunky compares the number with reviewed breakpoints rather than treating every TS plate as the same model: the TR2 begins at TS1, the TR3 follows after the TR2 production block, and TR3A production continues the sequence. The final TR3B changes to TSF and TCF prefixes, giving it a separate identification path.
What the decoder preserves
Original commission plates may include steering or equipment suffixes and may be written with spaces, dashes or other punctuation. PetrolJunky normalizes the entry for lookup while retaining the normalized identifier in the registry. Production ranges can identify the correct TR generation, but an exact registration year is only shown when the reviewed range actually supports it.
Useful for restoration and provenance
A correct TR2/TR3 family decode gives owners a clean starting point for comparing body, engine and build records without assuming that swapped components are original to the chassis.
