Clearly Macks are flavour of the blog at the moment....and Ron Johl has added his two pennorth with this picture and comment: "Hello Brian , having a look through my old pics i found these two old timer's first one is a Mack NM 6x6 ('A tiny of' lol) and a Karrier.
There was no problem in finding details on the Mack but found nothing about the Karrier.
The pics were taken at Stockwood park Luton , May 1994. The combat "N Series" were the first military 6x6 trucks by Mack. The NM-1 (87 built) appeared in early 1940, followed by the NM-2 (107 built) and NM-3 (104 built) all with enclosed hard cabs. The NM-5 through NM-8 did away with the metal cab, replacing it with the military soft canvas top. There was no NM-4 produced. The arched front bumper -- to clear a pintle hook -- first appeared with the NM-3. Approximately 10,000 of these trucks were produced in total The engine for the Mack NM 6x6 trucks was the 6 cyl. 707 cid Mack EY, that developed 159hp@2100 rpm and provided 530lb-ft of torque@1000rmp. The transmission was the 5-speed Mack TR36 and the transfer case the 2-speed Timken-Detroit T77. The truck had a net weight of 22,659 lbs., could carry almost 10 tons (never mind the 6 ton rating) and could tow 30,000 lbs. such as field artillery or ammunition trailers. A Gar Wood capstan winch was mounted behind the cab. The cargo body was steel for the NM-1 through NM-3, then wood. All the best , Ron. he then asks me: "PS. When did Commercial Motor stop using Bison hill to do their road tests?" Search me mate anyroadup click through here for the mystery military truck
So who knows anything about this then?
Don't know the make, but remember that "Dinkey Toys" made a model remarkably similar. I had a couple that my Dad snaffled off the sand table training models early in WW 2.
