The Bren LMG was developed from the
ZB26, a Czech LMG designed at Brno, by the Royal Small Arms Factory at Enfield.
The name was an amalgamation of BRno and ENfield.
Production began in
1937 at Enfield RSAF and it was accepted into service in 1938, when production
also commenced at Inglis in Canada and Lithgow in Australia from 1940. Daimler
and a corporation of manufacturs called Monotype also produced them. Others
were made at the Small Arms Factory in India The Bren became the centre of
all section tactics during WW2, and had it's own transport in the form of the
Universal (Bren) Carrier. It remained the standard section weapon long after
the war and soldiered on into the 1980's rechambered and barrelled for 7.62
ammunition.
In the interests of ease of production the design altered
many times during the guns service, in both large and small modifications, and
we have still to photograph a number of variations as they become available,
but this guide should give the novice the essential information to spot the
differences.
The Marks of Bren basically comprised the Mk1, Mk1m, MkII,
Mk3 (introduced 1944 for jungle fighting) and the Mk4 also introduced in 1944.
Postwar saw the Mk2/1 and the L4 7.62mm version. Further reading and more
information can be found in Ian Skennerton's '.303 Bren' and 'The Bren Gun
Saga'. In addition the Parts Identification list for 1947 is available from
ourselves in the SHOP and the accessories and stowage lists can be found in the
technical section of this site. |

 |
|
| The butt of the Mk3 and L4 |
 |
 |
| The Mk3 uses the K2 type carrying handle as does
the L4, note on the L4 the use of the Mk1 Cocking handle. |
 |
 |
| The Shorter length of the Mk3 barrel and the
bipod legs, which are mk1 in style except for the feet which are fixed rather
than extendable, the L4 is the same, using Mk2 feet, note the flash hider on
the Mk3 and Eliminator on the L4. |
 |
 |
| The Mk3 has sights graduated to 1600 yards
instead of 2000. The DP engraving stands for 'Drill Purpose'. The L4 is sighted
to 1800 meters. Note the difference in the magazine catch spring on the MK3 and
L4. The L4 almost straight magazine can be seen here. |
