Oil cooler diagrams

[SpaceKook]

Thanks again for everyone's help with this.
It's defintely a mix and match, only one pipe left to procure: 568989 . Might need to get it fabricated though as it seems to be a hen's tooth item.

Does anyone know how the actual cooler itself was finished, please? I've scraped off the layers of spider webs and it's pretty rough looking. Is it a silver paint or galvanising?

Once I had scraped the dirt and overspray off of mine, the tubes were plain galvanised underneath, but the frame was rusting, so must be plain steel. The magnet test would suggest that to be the case. I found a stray one when clearing out an old tractor shed at work, and it was the same under the green paint and grime.. I had mine carefully blasted clean and two pack sprayed in silver by a very nice man I know. (Hiya Rod! )
