only here I'd say - never heard of any model breakdowns of production on the old trucks - Gunnell sez about 65,000 trucks 5-10,000 GVW produced in 54 [170,000 below 5,000], and I'd bet very few were 1T panels- if you've one there in NZ [that wasn't recently imported used

], it likely came from Canada, w/ even less info available - got pictures?
