The Larkin Aircraft Supply Company (Lasco) was an Australian aircraft manufacturer based at Coode Island in Melbourne.
After returning from the First World War Herbert Joseph Larkin, a fighter pilot with the Royal Flying Corps, and his brother Reg Larkin formed an agency for Sopwith aircraft.
The original company went into liquidation and Herbert Larkin then started the Larkin Aircraft Supply Company (known as Lasco) in 1921.
It also designed and built a number of aircraft including the Lasco Lascoter in 1929, the first all-metal aircraft to be built in Australia.
Withdrawal of government subsidy, and economic depression, caused the company to shut in the 1930s.
