The Bob Semple
God bless the men in this machine! In 1940 war hysteria
gripped New Zealand and an effort was made to produce a home grown tank. It was
decided to armor an International Harvester* farm tractor to make use of equipment on
hand. The result was an amazing "tank" called a "Bob Semple" after a
politician in New Zealand. Bob was a popular, colorful, Labor politician (just like an
American Democrat - only worse). Backing this wonderful idea (probably because Bob was)
were the Prime Minister and Minister of Defence (who was Bob). Bob must have been
impressed by the U.S. Disston "Tractor Tank" and the idea that a tank would
actually be named after himself! Bob probably had visions of Semples storming the beaches
and taking Berlin or Tokyo! Rube Goldberg himself could not have designed it better. Apart
from being just plain ugly to the bone, the front gunner actually had to lay on a mattress
on top of the engine in order to fire his weapon! The Semple had a searing top speed of 24
km/h but had to slow down or even stop in order to shift gears. The "tank" was
highly unstable in movement and top heavy. The Public Works Department tried to give this
"white elephant" to the army and even offered to convert their entire fleet of
81 into Semples (at a cost of only 4200 pounds sterling apiece)! The army took them,
tested them, and even paraded them around the country in an effort to whip up morale.
After the laughter subsided, and in an rare display of military intelligence, the army
returned them (I am sure that they only needed to have knocked on Afganistan's door to
find a buyer as Disston did). Only 4 units** were built before public ridicule stopped the
production. The Bob Semple was armed with 4 machine guns, it was 12 feet tall had had a
crew of 8 men. 8 men? I can understand 5, but 8? 5 were probably soldiers, 1 was a shop
steward, another fended off the birds trying to roost, and the last took out the trash
once a day and waved to the people. There is a rumor that after the war Bob took a job
with Ford and helped to design the Edsel and fuel tanks for the Pinto. He later went to
Yugoslavia and influenced the design of the "Yugo" but this is not confirmed.
The reported weight was from 20 to 25 tons. The extreme swing in reported weight may have
been design differences between all 4 units** produced or incomplete historical data. The
production of this tank was not New Zealand's "finest hour".
*Janes reports that the type of tractor was an
International Harvester. The book "Pictorial History Of Tanks Of The World 1915-45 by
Peter Chamberlain & Chris Ellis state that the tractor was an International Harvester.
Another source, "New Zealand Yesterdays" by Hamish Keith, printed in 1984 by
Readers Digest Australia reports that a Caterpiller brand Cat DH-8 was used.

Digest Australia report 3.

NZ LPC
New Zealand built local pattern carrier was
based on the British Bren Gun carrier. The (later model) LPC No.2 was based on the
Australian Local pattern carrier No.2 which had 3 inch wide wheels instead of the 21/2
inch wheels on the British made vehicles.

The American M3 Stuart, Stuart 1
In 1942-43 the New Zealand Army was supplied with 292
"Stuart" tanks. They were a hybrid, with a M3A1 turret but a M3 hull, and with
the M22 37mm gun mount fitted to the M3 (the M3A1 had the M23 mount). They came with four
Browning machine guns but 5 mountings, so the co-drivers sponson mount was dispensed with.
It was suggested that the "Stuart Hybrid" as it was known was either from an
order to Russian requirements without gyro-stabilizers or from a production overrun of M3
hulls. Earlier hybrids had riveted hulls; later ones had semi-welded hulls.
The first 24 arrived in June 1942 - without handbooks, spares, radios and some
controls. They had been ordered by the British Tank Purchasing Commission in Washington,
and in July the British War Office advised that they were "unfit for combat"
because of omission of turret components! There were worldwide complaints, and details of
modifications done in the Middle East and Australia plus a list of modifications from
America were eventually obtained. Britain supplied some kits of "modifications for M3
Tanks" in November, but suggested local provision of the missing parts. As 48 Stuarts
were required for the 3rd New Zealand Division in the Pacific theatre, local manufacture
and fitting of the missing parts had already started. But the Division got Valentines
instead.
Jeffrey Ploughman in his definitive book "Armored Fighting Vehicles of New Zealand
1939-59" (1985) says that nothing could be found from local archives or U.S. sources
about why New Zealand got 292 defective tanks or when the defects were found. Fortunately,
they were not used in combat! New Zealand also got 89 of the M3A1 and 42 of the M3A1 scout
cars in 1942-43.
Found to be too light for combat use, they
were used as recce tanks without a turret. A total of 3 were converted to this
configuration. Other configurations were an Armored Personnel Carrier (13 converted), a
Armored Recovery Vehicle (nicknamed Rossie) (1 converted), and a 17 pounder gun tractor (?
converted).

The Schofield
Named after it's designer, E.J.Schofield of
General Motors Wellington. In 1940 New Zealand was in much the same situation as Australia
in that they were unlikely to get any armored vehicles from the U.K.and so had to look to
themselves. The only true New Zealand tank to reach prototype stage, and was based on the
chassis of the GM 6 cwt truck, and suspension units from a Universal Carrier. Armor plate
for the hull and turret was produced New Zealand Railways at Hull Valley Works. The turret
was open topped and mounted a 2 pdr gun and co-axial Besa MG. The truck wheels shares
common stub axles with the drive sprockets and idlers , and the change from wheels to
tracks was affected by pivoted arms operated from the hull rear. When operating on wheels
the track had minimum ground clearance and were kept clear of the ground with chains. The
Schofield tank was completed in August 1940 , but production was never started. Then in
mid 1943 the tank was shipped to Britain for evaluation tests, and remained in Britain
until after the war were it was last seen , the exact circumstances of it's fate is
unknown but was probably scrapped soon after the war.
