The 4.5" Howitzer

4.5

The 4.5" Howitzer dates back to before the First World War and was produced by Coventry Ordnance Works, it first entered service in 1909 and production stopped at the end of 1918 with 3,359 being built. Before the Second World War the carriages were modernized and 1939 it was supposed to have been replaced by the 25 Pounder but deliveries of these were slow and so some 4.5" Howitzers were used in France and others in North Africa. After North Africa the weapons were relegated to training duties.
