Historical information
This engine was a Commonwealth Aircraft Corporation (CAC) build, and had been upgraded to 92 specification at some time. This engine as acquired, was completely seized and great difficulty was encountered in dismantling it. The pistons in Nos 1, 13, 3, 2 and 5 had "grown" into the cylinder bores requiring some unorthodox methods to remove them. The cylinder barrels have been brought up to a reasonable standard, those beyond repair were replaced from stock. After getting various parts from the US, this engine was eventually brought up to running order.
