Who were the 17th coastal royal artillery regiment in World War 2?

The Royal Artillery 17th Coastal Regiment was formed in September 1941 from the coastal defenses at Tobruk in North Africa. The 17th RAR was part of the British 8th Army and served in Italy. One website says they were disbanded in July 1944. Coastal Artillery were formed and operated large, stationary artillery to defend important naval bases and ports. Since there was no longer a threat of attack by German warships in 1944, there was little use for coastal artillery.

I found one link that listed the 17th Coastal RAR as part of the famous British unit, the 7th "Desert Rats" Armoured Division during WW2.
