Not knowing what I exactly had bought, I put it on my website and asked my readers about it. The answer came almost two years later. Edwin Herkert and in the same week, Jeff Lewis gave me the answer. The Elbow Telescope M16 was from a M2A1 howitzer, which was mounted on an M7 'Priest' selfpropelled gun.

In September 2003, I went back to the museum near Port-en-Bessin. This time I got a confirmation it belonged to the M7 'Priest' that was displayed outside as part of the museum collection.

To give support to a fast moving infantry, it was essential to have a selfpropelled cannon. Experience with a 105mm howitzer on a Half Track led to the development to place a 105mm cannon on a full tracked vehicle. The M3 and M4 tank chassis (Lee Grant and Sherman tank) was an excellent choice. The gun was placed somewhat right from the middle in the vehicle. On the right side a distinctive round steel construction was created to house the .50 machine gun. Two prototypes (T32) were accepted in February 1942 and these were produced under the designation M7 Howitzer Motor Carriage (HMC). Because of the round turret, the British called the M7 the 'Priest, after the pulpit in a church.

The cannon, a M1A2 105mm L/22.5 howitzer, was operated by 6 men and 6 in reserve. Three were needed for loading, directing and firing. The driver and his assistant driver and the reserve gunner helped with unpacking and uploading the shells. The gunner left of the gun used a so called panoramic telescope (M12A2) and a Range Quadrant M4 to position the cannon sideways and in elevation during indirect firing. To give fire in a direct manner, the gunner used on the right side the Elbow Telescope M16.

M7

The first M7's that were produced had the M3 chassis. Later models were given the M4 chassis. The engine was a Continental R-975 C1 radial of 350 hp. It was for the first time in action with the British army. They had received ninety examples of the M7 in September 1942 and they were deployed during the battle for El Alamein.

M7B1

When the chassis of the M4A3 became available for the 'Priest, it was designated as the M7B1. The engine was in this version was a Ford GAA V-8 (450 hp).

On the outside the first difference you may notice to distinguish the two are the tracks. The M7B1 has extra wheels on the bogies for the top track, and at the front it had a smooth armored front plate. Both version had a speed of around 40 km/h and the radius was between the 160 and 200 km. The weight for both models was around the 25 tons.

In Helmond, Holland is a dedicated team working on the restoration of an M7B1. To follow the project, a website was created so you can follow it's rebuilt.

Sexton

Despite that the British used the 'Priest' with great success, they would like to see if one could be up-gunned with their own 25-pounder cannon. The Canadian firm Locomotive Works, in Montreal managed to built such a gun, a 25-pdr C Mk II , on a chassis of a RAM tank. This type, called the 'Sexton, came into service during September 1943.

It looked like the M7, but the big difference was the deletion of the round pulpit for the .50 machinegun, and the driver sat on the right of the vehicle. Of the Sexton 2150 were built before the production came to an end in 1945. It stayed in British service well into the fifties of the last century.

After July 1944 the M7 'Priest' was replaced by the Sexton within the 21st Army Group in West Europe. The obsolete 'Priests' of the 2nd Canadian Corps had there howitzers removed and were rebuilt as 'Kangaroos', the armored personal carrier. Between October 1944 and April 1945, 120 were converted as such.

M37
During 1945 the follow up for the M7 was introduced, the M37. The chassis came from the M24 'Chaffee' tank. The howitzer was a 105mm from a M4A3 Sherman. Despite it's weight of 'just' 23 tons, there was more room for the crew to work in. The engine was a Twin Cadillac Series 44, V-8 (220 hp) that gave the vehicle a top speed of 50 km/h and a radius of 160 km. There were 316 produced, but it never saw action in World War Two.
