Engine 51 and Squad 51 colour

[Wombii]

After some googling I found that you might be referencing a pair of classic american engines from a 1970's show called "Emergency!". Is that correct?

I don't know the exact answer, but if it helps at all, I can give you some guesses until the Americans wake up. Red Norwegian fire engines use RAL codes 3000 Flame red) and 3020 (Traffic red).

Going from photos on the internet of both those 51 trucks and newer US fire engines, I feel the Tamiya X-7 I've used on some parts look pretty close, but I'm not sure what the spray can TS equivalent would be. I think I'd look at TS-8 and TS-49.

And we love to see photos!
