Haha, I had to think about which was the ts as thats a sp400, and it was that colour when I bought it about 15 years ago. Probably what set me off
I just bought a can of own brand direct on metal olive green from the local diy place, and each year did a bit more as I always seem to be rehoming stuff thats battered and unloved and it stood coolant and use really well and it was easy to buy more to match.
Close but oh so far lol , i couldnt see the engine so it was best guess
