Indeed Adrian. I even have 298 from the same manufactuer and it's different.
It also differs on background and application method. And 2 years later looks different again.
I like my trailer in 298 (although i feel its a bit too green) and the snark doesn't bother me. It would however be nice to get a definitive answer but I don't think it will ever happen.
Tey restorations/jeep parts sell a 298 in cromadex which seems popular and used by various restorers. It is vastly different in colour to another 298.
Here's the colours plus some paint on the back of a bracket but from when I don't know. The truck was overhauled in 52 and then a base overhauled in 56.
BS381c 298 is a commonly used colour for British vehicles. Military vehicle paint supply a matt which starts satin but dulls down nicely. Goes on nicely without a primer but takes a while to harden.
My morris has some badly pitted loose needle roller bearings in the gearbox . None of the bearing suppliers can supply the size. Could dowel pins be used instead, would they be hard enough?
The cylinder head is (as far as i know) original, the freshly painted part is eau de nil. The rebuild date on the engine is 1956.
The two colours are a mile apart.
