I've read that
.Both 18-prs, Mk 1 and Mk 2, were superseded by the Mk 4 of 1920 but New Zealand carried on with obsolete equipments until 1941 when 25-prs were received

Anyone knows whether "18pdr MkIVP" guns http://members.tripod.com/~nigelef/18pdrsheet.htm saw service with Canadian, Australian and South African artillery? Or "18 pdr MkI,II" (with pole trail, recoil system on top of the gun barrel and pneumatic tyres instead of wooden wheels) were still in use till these guns (and 4.5" howitzers) were replaced with 25-pdrs?
