Keith, not to be pedantic, but the 2pdr IS NOT a Field Gun, rather it is a 2pdr Anti-Tank Gun. 2pdr Field Guns have not been seen in Australian service since the 1880's
Did John have an opinion if these Carriers are "Carriers, 2pdr, Tank Attack" mounting a "2pdr Anti-Tank Gun"?
I notice, too, that the carrier pictured has a nice growth of Lichen on it. Do any naturalists amongst us know the growth rate of Lichen? I believe it's quite slow, many years per centimetre or such.
