Looking for Spitfire radiator drawings

How much bigger were the Tropical Spits oil coolers?

Probably not much use but I found the following in an RAE report from October 1940;

The radiator bore the following identification data:-
Made by Serck Radiators Ltd,, Birmingham ”
Date October, 1937
Serial No. N5441
Drg. No. 30041/93
Issue M
Test press 15 lb/in.
Pat. No. 400720

The report is about why this radiator had started to leak when it it had only flown 41 hours in 21 months.
What really is interesting is the aircraft’s serial number it came from. K5054

What about those guys in New Zealand? Replicore , I think they are called.

Yes I already spoke with Replicore – no luck getting drawings from them unfortunately.

I don’t think they exist any more. I think they were reverse engineered by Gerry at Cambridge radiators (or whatever they are now!!)
