In

order to

overcome

the

disadvantages of the

two

man

turret

as

fitted

to

the earlier

marks

of Valentine a

three

man

turret

was

introduced.

A simple

expedient

was used

to

give more

room within the

confines

of the

small diameter turret ring. This was to move the

trunnions

for the 2 pdr. gun forward by 8" and the rear of

the turret

backwards by a similar amount forming an overhang . The gun was still

fitted

with an internal

mantlet, but the

turret front

was of a different design. By using the space formed within the turret overhang

to

contain the wireless set, sufficient r oom was

made

behind the 2 pdr. for a seat for the commander.

Above his head

was located

a circular rotating hatch

fitted with

a periscope . The hatch cover insisted of

three separate hinged sections so

that

the

commander

could

use his periscope without having to close up the

hatch completely.

This

hatch was

the

only

means of

entry

into

and

exit from

the turret

for

the

three

turret

crew members.

3/20

Because

of

the additional weight of the elongated turret

and

extra

crew

member

the thickness of armour

along both sides of the

hull was

reduced

from SO

mm

to 50

mm. This

saved approximately 8 cwt so that

although

the

new

turret weighed

considerably more than

the

original

the total weight

increase

of

the

vehicle

was

kept down to o ton.

According to

Vickers

Limited

the

design

of

a

three man

turret

for the

Valentine tank

was

instigated in

November

1937

and

entered production

in

1939.

f this is

the

case it is

difficult

to see

why

the design

for

a

two man

turret

with

2

pdr. gun

was ever put into production.

Despite

strenuous efforts by the author to

either

view

or

obtain

copies of

supporting

documents

to

ascertain the

true facts

the matter

is still

unresolved

along

with

various

other

problems.

It

could

be

that

the three

man

turret

was

part

of

the

original design

but

was

shelved due

to the gun

projecting

in front

of

the

vehicle. Whilst

in the

light

of

later

developments this

may seem ridiculous

it

must

be

remembered

that

before

the

War

no Country

had produced

tanks with guns

that projected ahead of the

vehicle.

This

was

in case a long

gun

barrel

would

be

damaged when the tank was

operating among st trees. n the United States the 37

mm

gun fitted

to

the

Light

Tank M2A4 was shortened

by

six

inches

for

this

very

reason.

The earliest three man turret Valentine

so

far identified is

T.S6591

which was

received

at the Mechanical

Warfare

Experimental Establishment from Vickers Armstrong Chertsey on 13th

April

1942. Stowage

diagrams are dated for 13th

July of

the same

year

all of

which tends

to

help date

this

mark

as

only

being

produced from

early 1942.

There

were

two

versions of

the three man

turret

Valentines the MK.III which

was

fitted with the A.E.C.

Diesel

engine

and

the

MK. V

which had

the alternative

G.M.C. Diesel

engine. Both

of

these marks were

externally

identical.

The

hull itself

was

the

same

as

the

MK.

II/IV

with

two

long

stowage boxes

on the

right hand

track

guard and spare track

links

carried on the

left

hand

front

track

guard. Auxiliary 30

gallon

fuel

tanks

were

standard

as were

five P.O.W.

cans carried at the

rear.

Valentines with three man turrets fought in the North

African

campaign

along with MK.II/IV

as well as

in various other theatres of

operations.

Out of

the

2

pdr. armed

versions

of

the Valentine the three

man

turret models

were

the ones selected for

conversion

to Duplex

Drive

Swimming Tanks. The majority

of

these

DO

tanks however were eventually only

used

for training purposes.
