The first task is to find what happened to the ship. Often RN ships are "mothballed" into the reserve fleet at the end of their service, then they could be scrapped or sold to another country and scrapped from there, either way ships bells were often removed prior to scrapping.
A search of the National Archive Catalogue revealed the last log of the ship [in document series ADM 53] was dated Feb 1962. Unfortunately the ship is not mentioned in any records after that date.
There are a few places where you may find help to identify the fate of the ship and/or the bell.

PS note for future reference re board etiquette, although there may be good personal reasons, posting all in upper case is considered equivalent to shouting and such postings are often ignored.
