A Westcountry Cases spokesman added that it was the first time the firm launched a telemarketing campaign. He said: “Sometimes, if you raise your head above the parapet things happen.”

The company also said that new customers had been attracted from outside the firm’s traditional south west market due to its competitive pricing. It has also completed its first export order to Holland.

“One significant factor is that we have been able to make far more competitive national delivery arrangements, while we continue to use own vehicles for deliveries locally,” said Heckford.

“As most of the news we hear is about job losses it is great to be part of a company where employee numbers are growing.”

Westcountry Cases is currently constructing two big cases to hold two sections of the hull of a frigate being built for the Spanish Navy, and has recently designed some packaging to transport the hull section of a submarine.
