Found this in a Govt. gazette, Jan. 1963. Appears that the Govt. purchased over 8 thousand pounds of DUKW and GMC spares from WH Hancock motors. So did Hancock buy the parts as surplus , then resell the spares back to the Govt. at a massive profit?

Hancock was still going in the 1970's , he had two warehouses in Melbourne ,
full of surplus vehicle parts. The Mitcham warehouse had Studebaker White Scout car and Diamond T parts , I went there scrounging many times.
