 Ordnance B.L. 60 pr Gun Mks 2 & 2* on Carriage 60 pr Mk 4P

 Picture List

 The 60-pr gun entered service in about 1910 it was further developed in WW1, notably 'production engineering' to simplify manufacturing.  It started being replaced by the 4.5-inch Gun Mk 1, using the 60-pr carriage, in the late 1930's.  They remained in service with some medium batteries until about 1942.  In 1935 Carrier Dial Sight No 14 was introduced to replace Nos 6 & 9 carriers and provide Probert pattern calibrating sights.   During the late 1930's they were upgraded to Mk 4P, being fitted with a new axle tree, hub brakes and pneumatic tyres for 'high speed' towing.  A modern, 'D' pattern, HE shell was also introduced, which was shorter and a few pounds lighter than the older models, and 'D' model shrapnel shells (Mk 3D 760 bullets, 41 per pound) were available.  It was used by one regiment in the BEF and one battery in N Africa, a few were provided to Australia in the 1930's.  Although named '60-pr', actual projectiles, both HE and shrapnel, varied between 56 and 60 pounds weight and 14.64 and 19.16 inches in length.

VARIANTS

 There were no UK variants, the Mk 4P was the last version.  However, South Africa designed and built a new carriage for 60-pr Mk 1.  This carriage was characterised by a pneumatic tyred two wheel bogey.  It was used in the campaign in Abyssinia.

Note 1, length includes 38 inch 'draught connector' extending beyond where a towing eye would normally be.  This connector raised the trail and lowered the centre of gravity of the gun to be best positioned for vehicle towing.
