Another WO number
 

WO18 is on a C15A belonging to Jeff (whose surname I don't know) in Queensland who has recently acquired a C15A.

Other details:

Chassis: 2844400325M

Engine: WR3816063

Contract SM2196

Can anyone shed any light on the exact type?

The M suffix in the serial denotes a Melbourne build.

'42 BritishContract for Australia
 

S/M 2196 was a 1942 British contract for Australia [2,484 units].

I wonder if any of these contemporary chassis were also to S/M 2196?
