Welcome F27 pax , I'm thinking you might of known Les Harbottle from Essendon all those years ago . I work with him at MEL airport , funny man the old Les.
You can get decals for the F-27 VH-CAT which operated out of Essendon , in 1/72 scale , it is the CSRIO scheme I think . You may be able to work then into a DofA scheme some how .
