Brian you still need to replace the oil cooler, find you one from here..
N.B. Brian I'm still want to ckeck clearly about this , because N. Africa F's.. most of them had the cooler replaced to late deep G type....not the blades....
:!:So if it is correct you can still use the one you bought....
1) Supercharger: "A new, large supercharger intake was introduced with the F-4 variant... However, the first production F-4s from WNF and Erla still retained the narrow supercharger intake..."
2) Oil cooler: "The F-4 originally carried the same shallow SKF 9-6130A oil cooler as the earlier Friedrich models, but the larger SKF Fo 927 oil cooler was introduced into service with the F-4/Z..."
3) Prop blades: "A new, wider VDM 9-12087A propeller blade design was introduced during F-4 production as well, but the earlier 9-12010A blades were still seen on early F-4 models"
Finally, "... all these could be easily retrofitted to earlier models in the field, with the possible exception of the wider VDM propeller..."
