The 68-pounder cannon was an artillery piece designed and used by the British Armed Forces in the mid-19th century. The cannon was a smoothbore muzzle-loading gun manufactured in several weights, the most common being 95 long cwt (4,800 kg), and fired projectiles of 68 lb (31 kg). Colonel William Dundas designed the 112 cwt version in 1841 and it was cast the following year. The most common variant, weighing 95 cwt, dates from 1846. It entered service with the Royal Artillery and the Royal Navy and saw active service with both arms during the Crimean War. Over 2,000 were made and it gained a reputation as the finest smoothbore cannon ever made.
The gun was produced at a time when new rifled and breech loading guns were beginning to make their mark on artillery. At first the 68-pounder's reliability and power meant that it was retained even on new warships such as HMS Warrior, but eventually new rifled muzzle loaders made all smoothbore muzzle-loading guns obsolete. However, the large surplus stocks of 68-pounders were given new life when converted to take rifled projectiles; the cannon remained in service and was not declared obsolete until 1921.
6-pounder gun or 6-pdr, usually denotes a 57 millimetres (2.2 in) gun firing a projectile weighing approximately 6 pounds (2.7 kg).
Guns of this type include:
The Ordnance QF 20 pounder (simply known as 20 pounder or 20-pr) was a British 84 mm (3.307 inch)tank gun introduced in 1948 and used in the Centurion tank, Charioteer tank, and Caernarvon tank. It was the improved successor to the effective Ordnance QF 17 pounder and the predecessor of the 105 mm L7 gun.
The 20 pounder's APCBC projectile had a muzzle velocity of 1,020 metres per second and could penetrate 21 cm (8.3 in) of rolled homogeneous armour (RHA) however these conventional rounds were rarely used. The armour-piercing discarding sabot projectile had a muzzle velocity of 1,465 m/s (4,810 ft/s) and could penetrate 30 cm (12 in) of RHA. The 20-pounder could also fire high-explosive and canister shot.
The L7 105 mm tank gun was developed from the 20 pounder. In 1954, the original version of the 105 mm was made by re-boring the tube of a 20 pounder barrel.
The gun was fitted to the Swiss pre-production Panzer 58.

I have a thankful heart that you have given me
And it can only come from you
There is no way to begin to tell you how I feel
There are no words to express how you've become so real
Jesus, you've given me so much I can't repay
I have no offering
There is no way to begin to tell you how I feel
There's nothing more I can say and no way to repay
Your warming touch that melts my heart of stone
Your steadfast love - I'll never be alone
I have a thankful heart that you have given me
And it can only come from you
I have a thankful heart; words don't come easily
But I am sure you can see my thankful heart
Help me be a man of God
A man who's after Your own heart
Help me show my gratitude
