FYI in case anyone is interested in my BRG saga...
I have a 1975 Austin-BMC-MG-Triumph British Racing Green on my car, painted by the PO. I think it is the perfect BRG to be honest. The car was originally Triumph Racing Green. One thing is clear, the paint codes are unclear. As I have done my research, I have come up with the following:
Triumph Original Factory Color (I guess the PO didn't care for this I think b/c it has just a shade of blue to it)
Year: 1966
Make: Triumph
Model: TR4A
Color: Triumph Racing Green
Factory: Code 25
PPG/ Ditzler: Code 43232
DuPont: Code 96778A
Paint presently on car (beautiful shade of BRG applied in 1999 to entire car by PO)
Year: 1975
Make: Austin-BMC-MG-Triumph
Model: Not specified
Color: British Racing Green
Factory: Code 75/6064 or HAA or 43
DuPont Centari: Single Stage Acrylic Enamel Code 43912A (code on the paint can the PO gave me)
Optional Codes: BLVC75 (others show it only as Code “75”)
BLMC75 British Racing Green
BLVC254
PPG/Ditzler: Single Stage Acrylic Enamel Code MAE45102
But, back in 2007 I was unable to get paint shops to match/mix this again even though I have the original paint can (Dupont Centari) with the Code 43912A. They can't seem to find that code in their books. Very weird!
So I went with next closest (for touch-up in the engine compartment) which was:
Paint Used For Touch-Up in Engine Compartment
Year: Unknown
Make: Jaguar
Model: Not specified
Color: Jaguar Racing Green
PPG/ Ditzler: Acrylic Enamel Code: MAE46169 A
I was told that, to a professional painter, the Jaguar Racing Green appears one shade darker than the 1975 Austin-BMC-MG-Triumph British Racing Green on the car. But, to a lay person they would never be able to tell. So, for engine compartment touch up it works.
Having said all that, in 2013 a new paint shop was able to find the code for 1975 Austin-BMC-MG-Triumph BRG as PPG Brand Code 924499
Hope this helps rather than confuses!
