Thanks I'm all over the info on the Maple Leaf forum. I only recently became aware that the RNZAF M-H 6x6 crash tenders had their bodies manufactured in NZ. Previously I believed they were purchased complete from Canada.
I'm planning to build a 1/48th scale model so I'm trying to determine just what form the imported chassis took as M-H utilised products from several different suppliers when converting the standard Ford truck chassis into 4x4 and 6x6 configurations. Unfortunately none of the 1942 M-H tenders have survived so it may not to be possible confirm many details.
