The Ferry Works factory was the manufacturing address of Rola Celestion Ltd. from 1948.

In the early 1950s, the radio rental firm RAP Radio, an offshoot of the radio manufacturer R.A.P. Ltd. was trading from shop premises at number 81 London Road, Croydon. 

Two of their radios were mentioned in Wireless World Aug 1935;

R.A.P. was registered as the general trademark of R.A.P. Ltd. in 1936.[2]

In the early 1950s, the radio rental firm R A P Radio, an offshoot of the radio manufacturer R.A.P. Ltd. was trading from shop premises at number 81 London Road, Croydon.

By mid-October 1951, 81 London Road was serving as both the company's head office and its South London sales and servicing department.

Benefits advertised to rental customers included a “splendid range of models” with “no big cash expenditure” and “no repair bills”. Installation, repairs, and replacement “valves and everything” were all free.

Despite all this, the company only traded for about two years in Croydon, leaving the London Road shop sometime in 1954 when it may have ceased trading altogether.[3]
